Reddit activated a word filter that whenever you say "fuck spez", your comment won't show up for anyone else. I just tested it on ModCoord. they're also deleting spez memes from the subs they nuked lo
the OP asked how are they gonna remove them all, so I replied they'll run a query for terms like "fuck spez". only to find my comment invisible, because they're already blocking it. spez protective word filter, it's active right now.
Power Delete Suite is probably the best I used. You basically just drag and drop a button to your favcorites bar that's actually a javascript applet (doesn't matter, just drag and drop it to your favorites bar and follow the instructions): https://github.com/j0be/PowerDeleteSuite
I personally had to use a fork version that added a delay between each edit, because the original one were skipping some messages due it "going too fast" on the api
