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..............
Would have had to save screens during the rate limit for that but it was a quite noticeable absence of noise and irrelevant results during, and when the limit was lifted it actually got worse than before it was instigated.
The thing is, you still get relevant results but with the noise increase after the limits removal, it's almost like some of it is being allowed to make people more aware of it....
