My forum is just a month old and our new members numbers never stop increasing, but my biggest worry are spammers which make up to 10%.

These guys are just too clever for me, i keep banning them but they keep coming back with a different IPs and host names how?

If may ask what are the spammers using to get a new IP and host name because i need to figth them to the end, they are ruinning by forum image by posting pornos and viagra stuffs.

From my investigation there email address finish with .cn and .ru which mean China and Russia, and there host names come from different countries which give me the impression that they connect to innocent people computer and send there spamming post from there.

My forum is a SMF.

Webmasters in here should help me out, Thanks.

Regards.

they are using a thing called a proxy

Some explanation please?

they pass through another system, which relays data between them and you in order to post , therefore the IP shown is the one of the other system (the proxy) not them

I find it difficult to understand you.

Ok, how do i figth them?

moderation is the only way

Disable posting live links, disable signature.

You can't disable signature in your forum, how do you encourage new members to register in your forum if you disable signature? all the top webmasters forums do allow signatures, it's another way of increasing your members.
