I'm going to make it so when someone hits a spam filter, they are automatically put on a "banned ip address" list.
then when they try to do anything, they will get a message that says
"you were catch for spamming, fill out this form if you want to prove that you are not spamming."
and display all the info on the "offending post".
once they fill out the form, they will be back with access to the site.
this means that I'm going to have to block a lot of annoymizing proxy cause it looks like they are using a lot of proxying addresses.
