I had setup a web site for a game I was playing a while back. Some time later the forum started getting hit with spam ranging from vitamins to pleasurable company.
I was curious about how much effort goes into keeping a site like Daniweb clean of garbage and spam. I haven't tried to promote my site at all and I'm already getting garbage on it, but I was wondering about the effort that is involved on your forums to keep them clean.
In addition, I was wondering if different forums are better at reducing the amount of spam your forum gets. For example, does vBulletin have better protection measures versus PHPBB (which my site currently uses)? The PHPBB one I use has the graphic image code a new user needs to submit, but obviously it isn't complex enough that image recognition can't break it.
How many person hours a day is just cleaning out spam from bots? Are there add-ons to assist with this? Are there blacklists that you subscribe to?
