I was aware of chickenado, thend1949, and Chachacoin17 months ago and had them tagged as merit abusers IIRC, but I removed my tag when I decided not to tag merit abusers (with input from the community).   Actmyname might have tagged them as well, but I can't remember.  So this hasn't gone unnoticed by any means, but DT members have basically backed off from suspected merit abusers.
