I don't know if part of Twitter's algorithm was to filter these out for me, but browsing Twitter without an account is a wild ride, and has led me to believe that the far right has indeed infested the platform thoroughly.
A lot of it did, and still does get removed/hidden that at least gives the impression that the platform is less toxic than it really is but I don't really buy the argument that forceful removal/banning is helpful anymore because it really hasn't worked anywhere online that ive seen, it just escalates things and makes them madder/more vengeful. Then they just make new posts/accounts/do damage elsewhere.
I'd much rather just read a few more empty death and terrorism theats and move on with my day than have twitter esculate them until they actually are mad enough to try and follow through with them.
