bbPress.org

for registrations i use bruteprotect it helps out alot.

bruteprotect + akismet = <3

plus combine that with bbPress’s spam control functions (throttle posting/time to edit)

bbpress uses the comment moderation settings https://codex.bbpress.org/moderation-and-blacklisting/

so combine that with the blacklist.txt from here and you should be fine
