The CAPTCHA security images used within Web Wiz Forums prevents any automated bots from posting spam.

What spammers do due to the increasing use of CAPTCHA will have sweat shops of workers in developing countries being paid peanuts to go around posting spam to forums.

As these are real people and not bots preventing them from posting is difficult without making it difficult for genuine members to post, as these people writing the spam are not stupid and will use things like proxy servers to hide their real location.

On this forum we use the 'Post Approval' system for new members so the first 10 posts need to be approved. This has greatly reduce spam where before a spammer would post in every forum, now they post in a single forum, realise that there post needs to be approved and so do not post in any of the other forums as it would be a waste of time as the posts would not be approved.

beatcaptchas has been successful in breaking many captchas
bots like xrummer are also being used to spam known to break captchas easily
successfully used for forum spamming. profile and posts.
macros like imacro can also be used to spam ( home made bots) and with beatcaptchas they work fast. Imacro fails with rich text box.

some ubots made bots are also able to do spamming ( fails with captchas)
imacro create accounts using beat captcha and ubot works after that.

above ip list confirms that some of the spammers are from that list ips.
But i also have many genuine posts from that ip range

i dont mind ppl taking advantage of signature
but atleast they should post something of value..and regularly participate

so minimum  number of post for signature and posting a link is what I will wait for.

to make my forum more user friendly i dont want to impose so many restrictions but disallow what spammers need link.
50 posts for a link is what spammers wont do
or a captcha for first x number of posts might work in some cases.

Not faced this. but threat for PM spamming is always there.
to avoid PM spam(xrummer, imacro, ubot)... another tool spammers can use... one minute gap between each sent PM and limitation on number of pms sent within 24 hours...

I have not used any of the above tool so not sure how successful they are.. but their online info seems they are really powerful...

I am also getting similar spams on my wordpress blogs.. even after all the (plugins)measures....so i have to depend upon comments approval. that is the last resort...

thanks everyone.. i have disabled posts editing also. so that later on they dont add link in the post.

Is there a way we can find links within posts? any sql query? so that we can find them in one go without visitng each thread? and remove links or content...?
