Myself and others I know of that have been using IPT for quite a while, never received any DMCA notices. If there was an infringing torrent that would result in a nice DMCA email the torrent would be pulled from the site.
Only public torrent sites like piratebay and such can lead to DMCA notices.
Been with TVT for over 10 years, 30TB (not a typo) worth of upload credit.
I would show a screen shot but their site's been down for almost two weeks :-/
Annual donor, dedicated 24/7 box, 65/15 internet.
Doesn't really affect me even though I'm an active member because I've never donated $ for credit points on IPT only download and seed.
RevTT is another different story. But I think the owner of IPT may also own RevTT. I've traced network traffic between various servers under the IPT and RevTT domains when the two sites weren't working for me one day and the trace led me to some Russian stuff.
EDIT: Still able to log in, got 3 invites again....
current user of IPT but would like to get an invite to RevTT. I have an almost 7:1 ratio and have been a member of IPT for a few years. PM me and I can send you a screen shot of my ipt account for proof
