All forums end up having a few spammers, some are just people who aren't familiar with forums, and may think it's like a chat room. I often give a quick warning to someone if they are caught using a forum as a chat room, and they usually stop. Some will get mad and PM me asking why I called them out. I explain the rules and usually they listen and go on their merry way. But are there any times where a user keeps spamming even after continued warnings? Have you ever banned someone for excessive spamming?
