I know how to download torrents and whatnot, but I don't know about getting it traced back to me. Last time I did, I got a message from Comcast saying not to do it again, but I can't help it.
Please don't answer saying "Just don't do it."
How naive you are about the internet, site server logs and ISP server logs.
Didn't you know that all ISPs are required by Law to hold records of all your internet activity for at least 5 years depending on which country you live in?
They can flag you for anything they want.
Also all site servers hold logs of when you logged in and out and what you did.
Also think about this.
If they can catch paedophile rings, chatroom groomers, serious crime organisations, terrorist activity and the like, several months or years after the event, people who know more ways how to bury themselves on the internet more ways than you have had hot dinners, don't you think they can find you and everything you've done.
They could trace you in the time of their tea break without even breaking into a sweat.
Using VPNs and proxies wont stop you getting traced either!
