Here's one I almost forgot:

Occasionally, in the transfers list - I will see people trying to download files from me that are 00% complete in my own download list. Of course, these requests end pretty much instantly, but at times it seems that I get hammered with them (when I have a real popular file queued but haven't gotten a connection yet).

I think that XoloX should not report a hit for a file (to other XoloX users) unless it has at least 1% of it.
