Twitter was being used by AI bots to digest millions of tweets to determine emerging narratives and to flag millions of "misinformation" tweets. They would then use this info to have tweets suppressed and form counter narratives. The rate limits that Elon implemented hindered their ability to do that ....
During the Rate Limit if you searched for France you got what you were looking for, when you do the same search now that the rate Limits is gone it seems like you get thrown everything and the kitchen-sink that just so happen to have the word france in it, fucking Cardi B visiting france, various k-pop and other accounts with france as a part of the name(including @* * * * * francine_ * * * * whatever), fucking ANYTHING that happens to have anything even remotely like 'france' anywhere in it..............
For the anonymous limit, they might be limiting network segments, not just individual IPs. So if you are on a VPN that shares an IP address with other users, or the limit is on the VPN's pool of IPs, then you might be sharing that quota with other users and/or bots. YouTube does this.
