i think most are on vancityads.. We are getting around 500 posts a day..alot of spam like CL.. we are working on stopping the spam
Try making them update with a reply post rather than a new post. REnew not New, and you can force it by moderating the section, so all new posts need to be approved. If it is repetitive for the purpose of top posting, just deny it or delete it, until they learn to stop spammng.
I see they are getting super clever by creating new handles for the sps they handle in the micros, so each one gets an ad, and each one gets a new ad several times a day, until the point where all you see are micro ads. duttslist was trying to find a fix for that, if they were spamming, they'd get their ads deleted and forced to pay for a single agency ad. You can actually see a few of them on that site.
After that, maybe work on requiring ads to be tasteful rather than trashy, and we can say goodbye to the CL style of crappy titles with sTuPiD hiGhScHoOL whirls and twirls and ridiculous symbols and punctuation.
Well, we can dream.
