Ok and thank you for replying.
I agree. To my mind, PunBB should develop some tricks to close the doors to suspect posts ; at least make spam more difficult.
Turning off the guest posting is a solution, but it is also the proof there is something wrong. Go fishing is another solution
In my idea, the task of the parser shouldn't be limited to formating the post : why not use the parser to evaluate the message ?
For example, count the numer of «http» in a post ; if there are more than, let's say, 2, so make something (pre-moderation or, easier, ask for a confirmation/verification) ;
More difficult, I suppose, a bayesian filter maybe a good solution.
What is the purpose of spam : links !
So, make something that block posts with more than X links and ask for something for confirmation.
Or, for example, say the users the links must have a special form (special bbtag for example), so that spam messages with regular links will be automatically blocked. (and don't make the parser recognize the non-bbocded links).
Last, this would be very convenient and usefull against spam, but not only : develop a script for administration to delete all what we want with numerous filters : message(s), user, topics, date. By word (from title, from name, from message), by id (delete all messages, or all members, or all topics from id X to id Y). Don't forget a «select all» box.
Ah, what surprised me, is the spam mentioned above, is the fact a banned name is able to post. How possible ?
