Khaos77 is 100% Zin-Zang.  Not a doubt in my mind.  I'm curious about your thought that aliashraf is Anonymint, though.  I didn't get that impression, although I can see some similarities.

I'm also interested in where the banned accounts RNC and anti-cen fit into the equation and whether those are more Zin-Zang/Khaos77 accounts.
