First off, she and Scriabin were always at odds.
Also, in her Ask Skippy thread, she made jokes about spying, which made Lubab very uncomfortable, as JDL had snitches in the past. At one point, Skippy even called Lubab a "b---ard" on Facebook when he tried a make up with her.
Skippy has also argued with Bullcat3 and Mills/Yehudit. She has called Yacov a liar in a private message, and she also called Shlomo some names as well.
So being how sensitive the global mods and admins are about anything resembling missioning, that post about the messianic Jewish woman was the last straw for Chaim. (It would have actually gotten anyone banned.)
