Selling accounts without IP bans, allowed over Tor and allowed to post everywhere within the rules would be more interesting.
I don't think that is such a good idea.
Why not? Aka donators account and provide several methods for payment, paysafecard, ukash, BTC of course, what else you like and people need.
Shared accounts also aren't.
Yeah, forget about shared accounts. They do no longer work as soon as too much trolls and spammers are around.
I had no problem registering with Tor. I must of been on a fresh node.
That won't work well if they use [https://www.torproject.org/projects/tordnsel.html.en TorDNSEL] (official list with all tor exit nodes) what most tor blocking sites do. You were in luck maybe because of some bug the node wasn't listed.
