I recently send some BTSX to BTER and noticed that a number of accounts have been registered designed to catch typos.  Such as:
bbtercom 
bter
bter-com
bter-bts
bter-deposit
And a bunch of others.  BE SURE TO FIND btercom AND ADD IT TO YOUR FAVORITES and then only send to what you pick from your list.  A typo could be quite costly.  It's possible BTER themselves created a bunch of accounts with common typos, if so that's awesome, but unless they respond and say so it could be a scammer.
