Tracing the culprit.

Hey guys, if you have someone's email, say for instance a random douchebag, because they were stupid enough to spam it everywhere in some fucking chat, or just let you have access to it, is there any way that they can trace you if you sign them up for a load of different shitty, and most likely, free porno sites, just to fuck with them? Just wondering.

Nope, not without getting the cooperation of the sites or authorities, who likely can't be bothered.

Thank you. I shall now proceed to porn spam those I hate to within an inch of their lives.
