How to prevent spam links to be posted?
Hi, one of my forums get abused by a lot of competitors. Basically they posted spam links to new threads and they just keep coming back with new IDs. Maybe they hire paid posters to do this. I want to know if there's any plugin or something that can prevent some specific links to be posted? For example, I want when someone makes a new thread/new reply with link to "xxxxxx.com", the post won't be visible to users (or even deleted automatically). Please tell me how to do that?
