@hilariousetc,can you please request theymos to implement or at least consider this :-
There is this thing which detects your original IP even if you use VPN or anything, so if you're banned, you cannot access your account/s even if you use VPN. Simple as that. If this feature gets implemented, then people won't have to fuss about shit posters.
I had mentioned this in another thread couple of days ago
I don't know what "this thing" is, but a good VPN won't allow any scripts to detect your real IP address, and neither does Tor.
Bitcointalk has units of evil based on IP addresses, it's not perfect but it's something.
I know it's annoying and frustrating but all you can do at the moment is keep reporting them and staff will keep on nuking them.
Don't worry there, I'll keep reporting them

I've never heard of this either. Tor and VPNs are meant to protect you against this sort of stuff and I doubt even the CIA can find this info if you're smart enough (though I believe VPNs can accidentally leak your IP in some ways). What you might be thinking of is browser fingerprinting though which can be very useful to catch alts and just using a proxy won't help you (and I think this should be on the new forum). You might use a different IP for your accounts but you almost certainly won't be using a unique PC or browser for each of your alts and accounts could be collated and searched by them and cross referenced with other data etc.
