Right now, I can do about two searches on xcancel before it gives me the "instances have been rate limited" message. Then if I completely close out of my web browser, clear my web history from the last hour, and go back into my web browser, I can do another one or two searches, before xcancel again gives me that message about ""instances have been rate limited".

In theory I can still read the same things I could read before on xcancel by doing an endless cycle of doing one or two searches, then closing out of my web browser and clearing history, and then going back to xcancel and doing another search or two. But certainly that process is very annoying.

Now, I'm not 100% sure if this is related to Musk's cease and desist letter. I've run into this problem or similar technical problems about twice a month before when using XCancel. Usually the technical problem is resolved within 2 or 3 hours and I can use xcancel normally again. So I guess I'll check back in a few hours and see if I can use xcancel normally again.

Edit: Xcancel is working perfectly if you first go to somebody's X profile, and then you turn the x in the url to xcancel. For example, here is Elon Musk's profile on xcancel, where you can still view Elon's tweets, Elon's replies, and the replies that people have made to Elon's tweets.

XCancel still has a problem right now where I can only make a few searches on the xcancel website itself before it tells me I'm rate limited, and I have to sign out of the browser and sign back in before I can make searches on xcancel again.

However, I occasionally have had this problem on xcancel even before today. And I'd assume that this probably isn't related to the cease and desist letter. If this was due to the cease and desist letter, I'd assume that xcancel would be completely down right now rather than having limited functionality.

Make it easy on yourself and just use Tor. Clearing everything is a matter of clicking on "new tor circuit for site".

Some sites throw annoying captchas your way though.

You're doing voodoo. It's not you that's being rate limited, it's xcancel itself that is being rate limited. If you wait a few moments and reload, things will likely work.

Although now I should say that this was the truth yesterday, but now twitter seems to be actively killing the credentials that nitter instances are using, and they're returning rate limit messages permanently. My guess is that this is a function of how many credentials/tokens a nitter instance was cycling through to get content x the amount of traffic that nitter instance gets. They probably just set the rate-limiting bans longer for everybody (or steadily increase them on each offense), instead of trying to find the specific offending credentials.

edit: xcancel officially gone, so none of this matters.
