Indeed...  and in most cases, it's really really bad poker.

I had a session in 20/40 one night where one opponent derided me all night on my "bad play".  I pretty much had him pegged and figured the best way to beat him was to play hands that would give me the best chance of taking his stack when they hit.  As such, every time I beat him, it was with "terrible" starting hands.  To him, it seemed that every time he got his money in, I hit with terrible hands.  That's pretty much right.  I folded hands that didn't give me enough value before they had a chance to hit.

At the end of the session I had won 4btc from him and he left bitching about how the site must be rigged.  The reality is that he was partially outplayed with the remainder being unlucky enough not to hold against my 13-19 outer draws.
