stop the spamming

[JD1]

Manual approval after an introductory post may help as well, although it would also be time consuming for the person having to do the approvals. If you limit members to only posting an intro until they are approved that may keep some of the computer spammers out or at least keep them just in the intro section which might make for easier housekeeping.

One forum I use does the above but also doesnt post the intro until it has been approved which probably helps more but is no doubt even more time consuming and may put off potential new members

It doesn't look like there is an easy answer
