I tended to use Twitter as a local news aggregator so my feed doesn't have as much spam as some users. What pushed me out the door though was the adverts. I don't mind ads, but since the big brands left Twitter all I am getting are scammy crypto ads because I once commented on a Medium article about it or gambling ads.

I have long maintained that internet tracking for ads is largely useless because it shows you things after the fact rather than trying to predict what you might want. But X's ad tracking is so bad it shows me things I would never invest in!
