i see no problems with the way you are describing the situation.

i can search the gnet for something and you might respond with a query response, aka "hit", but i do not have to download your file that you are advertising to me. because i am a picky user (not a common mind-set that luser filesharers have, but eh.) or they just picked the file that had the most hosts. all-in-all, its nothing to worry about and its left up to the user whether or not they will download your file.
