Any solution for PM spammers.......?

If you have email authentication turned on and don't allow signups from yahoo, hotmail, and the like, you should have a valid email address that you can use to track down the webhost or isp they are using.

Most hosts and isp's are very happy to terminate the accounts of people who are proven spammers.

are you meaning sending or all togther?

if not allowed to view, or send you could set a veriable within say config or group table that holds the number of days/post sor what ever.

do if postCount/Regdate < group Required Posts/Date then blnPMSystem = False

there is a veriable that enables/disables the pm, system you could disable it if the user is not allowed

also use a suimular method if just preenting sending. but do it on the pm pagres not to show the new message button, and also check on submit of the page,. and return an error message
