@tom it is not meant to bring up captcha after every posting ........what i meant is that the plugin should

1.it should scan every comment or posting that contains spammed links......e.g if a spammer post a spamed lets say 5 within 15 seconds it will bring the captcha up and at the same report to admin or if possible report to i.p blacklisting databases.......

2. if the spammer continues it should ban the spammer from posting for like an hour .......

@moneya: and how should the plugin know if the link included in a posting is a spam link or not? A link as such is not necessarily a sign of spam.

And the time threshold (more than X new posts in less than Y minutes) is exactly the approach the Spam throttle plugin I linked above already has implemented.

this is the idea....from what i know....only a spammer can post up to  lets say  5-10 links within 30 secs  interval.....

2.i would like to know if spambots can read animation.......

sorry for double posting

i do not require my members to use captcha only when joning : )
