To be honest, I'm super annoyed by accounts that are basically only cross-platform retweeting. If all your mastodon contributions start with "RT @somebody@twitter.com: …" … what are you doing here? Could you at least post those as follower-only?
@deshipu Not quite that easy – some people do the twitter-crosspost thing in a rate that works for me, very selectively, and I wouldn't want to miss that.
But thanks to @deshipu, I now have "^RT @" as a filter for just my local timeline, which is where this annoyed me the most. So I'll still see RT toots from people I've chosen to follow, but not on my chaotic home time line. Works for me.
@rixx I think you can easily add those as keywords to your blocklist.
