I've never used IPT but i am downloading from thepiratebay n torrentz2 but torrentz2 it's virus as hell xD i got lot of viruses from there and always formated my computer also i lost lot of projects c#.net java and others pfff.... Seriously when i want a program or something to get done my job it's hurting me, cause i bored to create a virutal machine yea, but even if i create it i think virus it's able to get access into other disks as well.... So yea the most secure it's thepiratebay.
