Seems remarkably similar to [https://xkcd.com/1897/ this comic]. Is he running out of ideas? [[Special:Contributions/162.158.146.166|162.158.146.166]] 00:33, 14 November 2019 (UTC)&lt;br /&gt;
: I don't see much connection, other than them both being about CAPTCHAs.--[[User:GoldNinja|GoldNinja]] ([[User talk:GoldNinja|talk]]) 00:54, 14 November 2019 (UTC)&lt;br /&gt;
::agree GoldNinja the first is about captchas getting freework done, the second is about that work having potentially malicious consequences [[User:Boatster|Boatster]] ([[User talk:Boatster|talk]]) 04:50, 14 November 2019 (UTC)&lt;br /&gt;
:::I agree that Randall uses a similar idea, but he uses it in two very different scenarios. The first is a bit scary as it relies on somopne using this captcha before the cat crashes, but this comic is much more sinister, especially the title text. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 09:10, 14 November 2019 (UTC)&lt;br /&gt;
::::I see you're using the car --&amp;gt; cat browser script ([[1288]])... I approve. &lt;br /&gt;
::::[[User:ProphetZarquon|ProphetZarquon]] ([[User talk:ProphetZarquon|talk]]) 17:08, 15 November 2019 (UTC)&lt;br /&gt;
:Actually, I agree on the similarity, both are about CAPTCHAs being used for nefarious purposes other than the supposed intent of identifying humans vs. bots (this explanation is the first I hear that Google openly uses CAPTCHAs to train AI, is that actually confirmed? If I ever saw a Google CAPTCHA I'd make sure not to solve it, LOL!). Just that 1897 is more mildly nefarious, just asking something a self-driving car should already know.

&lt;br /&gt;
A note: [[2227]] isn't connecting to [[2228]] via the Next button; has this happened before? --[[User:Account|Account]] ([[User talk:Account|talk]]) 01:20, 14 November 2019 (UTC)&lt;br /&gt;
:Fixed now.--[[User:Account|Account]] ([[User talk:Account|talk]]) 02:49, 14 November 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
Why is this comic listed as a Thursday comic? Isn't it Wednesday in Boston?--[[User:Account|Account]] ([[User talk:Account|talk]]) 02:49, 14 November 2019 (UTC)&lt;br /&gt;
:Yes. I don't know what time the comic was uploaded, but right now it is 10:34 PM Wednesday in Boston. I changed the date of the comic to today instead of tomorrow. [[User:Mathmannix|Mathmannix]] ([[User talk:Mathmannix|talk]]) 03:34, 14 November 2019 (UTC)&lt;br /&gt;
:: Well, this site uses UTC time (something I somewhat disagree with, since I think it's a time zone that lands in the middle of the ocean, LOL! But clearly to be fair to people in different time zones, so I can't argue it as being the best choice), so maybe our site got it late enough that in UTC it was already Thursday? [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 04:33, 16 November 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
I think the upper right picture looks like a cave, but maybe too angular to be natural; maybe a bomb shelter or something like that where those pesky humans might actually try to hide? [[User:Mathmannix|Mathmannix]] ([[User talk:Mathmannix|talk]]) 03:40, 14 November 2019 (UTC)&lt;br /&gt;
:I was thinking a bomb shelter or bunker as well [[Special:Contributions/108.162.212.173|108.162.212.173]] 03:44, 14 November 2019 (UTC)&lt;br /&gt;
::That sounds about right; just made it official on the transcript. --[[User:Account|Account]] ([[User talk:Account|talk]]) 04:49, 14 November 2019 (UTC)&lt;br /&gt;
::: Bomb shelter or looks more like one of those hanger-in-a-hill things you see in movies. To paraphrase Star Wars, That's no cave. :) [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 04:33, 16 November 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
I wonder if the section on the text case used for CAPTCHA should be moved to a trivia section, since the differences between here and xkcd.com is simply related to standard comic title convention and the font styles applied on each site. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 16:04, 14 November 2019 (UTC)&lt;br /&gt;
:I agree with that-- or perhaps it should simply be ignored; after all, this wasn't mentioned in KSP 2.--[[User:Account|Account]] ([[User talk:Account|talk]]) 16:23, 14 November 2019 (UTC)&lt;br /&gt;
:: I indeed find it a rather petty and pedantic point. I really doubt Randall took his all-caps font into consideration, he simply wrote it technically incorrect (it's just a coincidence that the font makes it look almost normal). In the end it's quite common to write an acronym like a word, without capitalization: Scuba, laser, taser, gif, lol (and its variants), etc. Count me as another vote for a Trivia section, it's a nice note to make, but barely worth noting.

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1969&lt;br /&gt;
| date      = 19 March, 2018&lt;br /&gt;
| title     = Not Available&lt;br /&gt;
| image     = not_available.png&lt;br /&gt;
| titletext = If my country ever picks a new national flag, this is on my shortlist for designs to argue for, but I think in the end I'll go with the green puzzle piece or broken image thumbnail.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Update content a little bit further. &amp;lt;small&amp;gt;Do not remove this tag too soon.&amp;lt;/small&amp;gt;}}&lt;br /&gt;
&lt;br /&gt;
A very common, yet frustrating issue on the {{w|internet}} is finding a broken link, taking you to an &amp;quot;{{w|HTTP 404|Error 404}}&amp;quot; page. The purpose of the page is to tell the user that the content they were looking for has been either moved, or deleted. Randall suggested replacing the standard &amp;quot;page not found&amp;quot; text, to &amp;quot;This content is not available in your country&amp;quot;. This could fool the user into thinking the media they are looking for is actually there, but is {{w|Regional lockout|region locked}}. Using a {{w|VPN}} and/or {{w|Tor (anonymity network)|TOR}} to try and access the content from another country wouldn't work, because it isn't actually region locked; it is just an error 404 page, wasting even more time, most likely frustrating the user a great deal in the process.&lt;br /&gt;
&lt;br /&gt;
The title text suggests setting the picture as a national flag. This would be very ironic, as it would suggest that the country's flag itself, something that is used to represent the country across the globe, is region locked. The country in the title text likely does not refer to the United States, but rather to the new country featured in [[1815: Flag]]. The first flag of this country included a phone notification bar, so changing it to a &amp;quot;page not found&amp;quot; icon would continue with a trend of technology imagery. Instead he argues for a green puzzle piece, which is Firefox's and Chrome's &amp;quot;plugin is missing&amp;quot; icon. He also argues for an equally frustrating broken image icon (which is used in lieu of a photo that is either missing or incompatible with the browser).&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[A gray box shown on a black background says &amp;quot;This content is not available in your country.&amp;quot;]&lt;br /&gt;
:Caption: If you ever ''really'' want to make people mad, set this as your 404/&amp;quot;Not Found&amp;quot; page.&lt;br /&gt;
