I don't allow self promotional posts on my forum, but do allow people to post links. I have a "read this before posting" and some people honestly don't see it or don't understand how forums work. For them I will post a nice reply and possibly edit the message for them.
If it's obviously spam it gets deleted, period.
But what about the usernames? I can delete the messages but there's usernames that are registered that still have links going to these spammy sites. How do you delete users in phpbb? Or should I even be worrying about this and just leave them there?
What do you think? How do you handle forum spammers?
