Blocking over 300 including ALL town/city communities because they are ALWAYS negative BUT Lemmy Connect also lets me filter (hide) on regex for communities and posts. This is invaluable to me- I was going insane trying to keep up with the arms race of cross posts to identical or near identical named communities on endless new instances.
Posts filter:
/elon musk/, /heathcliff without heathcliff/, /neuralink/, /furry/
