He cross posted to "get" another poster.  What part of that are you having
trouble understanding?  Mr. Chung has made a point of saying he doesn't
originate cross posting, and he didn't do it this time just to be a "nice"
guy and make sure the fine points of his argument wouldn't be lost on a
wider audience.  He followed a poster on one group into another, what part
of that is not trolling and stalking?  His retorts are endlessly mindless
in their sameness, acid remarks of no substance but just words to have a
responce, any responce to save face; we don't need more of that drival on
multiple groups at his instigation; trolling and stalking.  He was caught
at doing what he saoid he doesn't period.  I understand the shame he fells
and the desperate urge to save face, but he only compounds the original
act and highlights the shame and folly of his weakness in these matters.  
It is character we are discussing, his behavior in this regard will well
define his.
