Taking preventative measures, is there a mod that prevents users from posting links if they are under X posts? Or is there a setting in SMF that by default is already there? I have noticed tat spammers all the time put links in their first post.
There's this mod that will do what you are looking for- http://custom.simplemachines.org/mods/index.php?mod=2404
You're going to have to emulate to version 2.0 RC4, 2.0 RC5 in your package manager. Here is how you can do that- http://wiki.simplemachines.org/smf/How_can_I_install_a_mod_that_doesn't_work_in_my_SMF_version
Once the package installs with emulation, you can then go back to revert to your actual version and the mod will still work.
