Got it, thanks for the tip.  I don't think any particular
discretion is necessary in this forum (short of insults 
and/or libel, of course), particularly since
what you originally asked looks fairly innocuous and 
non-combative to me.

What I will do is just avoid doing any business with 
CelMart and Anime Paradise.  Even if you'd actually worded 
your question to the tune of "Say, do you folks think this 
is fake?", it would be hard to characterize their behavior 
as anything but bad business practices.  I don't think I 
need to be dealing with a vendor who reacts this way to one 
guy making a remark on an online forum.

Again, thanks for the tip.  Cheers
