I have deleted so much spam over the past week, probably over 150+ already. I can't delete the users though and I don't get post reports as I'm not a mod. I usually keep the web site open in the back ground, and check every now and then. I really hate when a spammer has like 20+ posts grrrrr. The other day was the first time where I seen pornographic images, all 12 posts of them.
And this quote from Klute is the best help I can ask for:
One thing we can all do though is not post anything after a spam post as it makes them harder to spot.....
