In today's online world archiving services are the best way to keep and provide evidence. Being able to view deleted tweets to checking if an online publication is editing its content by comparing it to the archive. One of the most used online archive services is archive.is which Twitter is now supposedly blacklisting from their platform.

Attention to this was brought up after Twitter user @BravingRuin and journalist Nick Monroe tweeted out for confirmation by other users if they experienced archive.is links being blocked in tweets or DMs.

These links are one of the only ways to prove the existence of posts, articles, etc after they have been edited or deleted. They are critical for documenting evidence online. pic.twitter.com/Qvp6hFpm0C

I have to inquire about this, sadly.

Can folks confirm that archive(dot)is is now blocked by Twitter? I can't even use it in DMs anymore.

Multiple users replied sharing screenshots of their failed attempts to tweet out links from archive.is with Twitter giving them an error messages that reads, "This action was flagged as suspicious" or, "This request looks like it was automated. To protect our users from spam and other malicious activity, we can't complete this action right now. Please try again later."

Where is the option to confirm it's not an 'automated message', @Twitter?
You force us to use @Google's horrible captcha system to unlock our accounts when we are flagged for the suspicion of 'automated messaging'. Why not here? What are you afraid of? pic.twitter.com/fwU2EliuIw

List of more tweets available on our Twitter Moment: Twitter Blacklisting Archive(dot)is Links From Platform

It seems that Twitter has blacklisted all URLs that contain the archive.is domain from their platform for an unknown reason. However, there is a way around the supposed blacklist as Archive.is has other domain extensions for the website, meaning you can replace the ".is" with ".fo", ".li" or ".today" and the link will work on Twitter.

I reached out to Twitter for comments on this matter and have not received anything from them at the time of publication.
