invite share and private torrent sites

well i was on lifehacker and i saw mention of inviteshare.... i had seen it before but apparently its gotten alot bigger

i mean it looks cool and all i guess but i can't help but think that some private torrent sites might be getting pissed....

particularly ftn and bitmetv
ftn has full url listed and from what i've heard thats a "no"
bitmetv i was more surprised about.... according to the site 60 invites have been sent(lol wish one was to me but i don't really trust the site and i don't want my email shown to public ><)....

i mean bitmetv will ban people who don't even trade invites but rather give out invites on here right?
but here your username on the torrent site and email can be very different from your fst account name, whereas on inviteshare the emails are clearly visible to anyone with an account

so i guess the point of this whole thing is to ask all of your opinions on the matter....
