if i use tor ?Yes, they can track you quite easily. But...will they track you? That depends on what site you are talking about of course. All social networks, email providers etc are fully aware of VPN provider IP's....especially any of the free ones you might be considering. Other smaller/newer sites might not (yet) be checking them...but undoubtedly will eventually.
Same difference. Exit nodes are flagged/blacklisted too and they're really slow.if i use tor ?
what you recoment to do?I think they can since most nodes are somehow identified.
