Unfortunately I'm afraid it's too late..   These people are in and nothing is going to get them out.. There  highly automated, and will send out
page after page at a click of a button.  In some cases it's   completely  automated, once they have programmed  to selected forums.  Thinking you can somehow block there IP addresses, , is  a waste of your time,  It's been reported elsewhere that they have hundreds of  active IP's simply waiting to be used.
It's a bit like trying to beat "Wack a Mole"
I know of one  forum  [the subject is unimportant ]  where they shut down the site for  6 months , and when they reactivated it they where back to
where they were before the shutdown.  The site no longer exists
