There is all species of trash on Twitter now. It is usable only due to a vast and constantly curated block list. And then Twitter doesn't filter hashtag searches using my blocklist, so they are increasingly unusable. The ads are all stuff that doesn't mind showing up next to neonazis. Just today I got an ad - a large display ad, not just a "promoted" tweet - for an obvious investment scam. 10 seconds of dd on the ad would have revealed that.
