There's a user that joined yesterday, has posted two threads, one of which I deleted shortly after and the other he posted the following day. When I click "Spam", I have all the "Spam cleaner actions" checked by default. When I click "Clean" it displays "No matching users were found.". Which normally means job is done, but not this time. It literally doesn't do anything for me. His thread is still there and he hasn't been banned. I've tried several times to do it and same result. My only option is to manually delete his thread and ban him.
