Only thing I posted today that I recall was well wishes for the disabled niece
did you click any DUmp links here at CC that take you directly to DU?
you need to avoid that as well. it shows up as a referring source, and if they are mining the logs (and I am positive they do on occasion at least), you can get busted that way as well.
outside of that, their "mirt team" may have just been suspicious and canned you. you can't be overly agreeable there, nor overly obnoxious... not until you have a massive post count at least. I *think* I have a good method going, but I'm not going to share it here and potentially give myself away. my current mole has considerable time under his belt now and has survived longer than any of the others, but i step lightly on certain subjects.
