  Yes, spam bots are not such a big problem but I too see the human spammers all the time. I participate on a number of very active forums and the way we deal with them is to delete the posts right away. IOW, there needs to be an active administrator on the forum. It seems to be the consensus that there isn't a better solution. Too bad.
  I hate spam, but also like to look at the positive side of things. Of course one can see spam anywhere, but when I encounter a new forum and there is very much of it, or it stays up for a couple of days, then to me it indicates a lack of interest on the part of the owners. So, to me, spam can also act as a useful indicator.
