I don't think it happened in a direct action to 
try and avoid getting feedback... A while back 
ago, I bought some DVDs from a Canadian seller. 
They ended up getting lost in the mail; 
fortunately, I had taken the insurance, so the 
seller replaced them. However, the turnaround 
time was so great (2-3 months?) that by the time 
I got around to trying to leave my feedback for 
them, they were no longer a registered user. I 
think Ebay had suspended their account for 
promoting their sales website a little too 
enthusiastically, apart from their auctions.

So, yeah, it has happened before, but I don't 
think that people go out of their way to get 
suspended. If they were going to be dishonest 
about it, they'd probably take the usual route of 
working up an acceptable level of good feedback, 
then really hurt a bunch of people all at once, 
and pop up later with a new account. But just 
because someone's deactivated--- especially 
deactivated with their good credit intact--- 
doesn't mean that it was related to an unhappy 
buyer's complaints. :o)
