Myrthos,
this makes sence indeed, if the spammer's goal is to get easy posts count fast
What are you doing with those, who don't care, just offend for their pleasure?
Yes, in this case mods are thoroughly studeing everything that is written and take the measures accordingly.
At RPGDot we also have a warning system. 5 Warning and you are banned. The system also includes an extra button on every post, which, when clicked, sends an e-mail to the moderator who can then check out the post and can take the appropriate action (if any action is needed).
The moderators at RPGDot are expected though to read all the posts. That's where they are moderators for, the button is just to signal them quickly.
Of course the button is sometimes pressed by accident and sometimes the reason is not valid, but overall it works fine.
In some occasions we had some idiots on the forum who didn't make it to 5 warnings, they got banned before they reach that point. At a certain point this was so bad that I installed guardians at the forums. A group of 3 that had access to all forums, so they could moderate them in case the real moderator was not there. Afterall moderators have to sleep too <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
