I had a new credit card number stolen online and used to download porn and it ended up being a funny story. It's possible the credit card and the porn site were in cahoots but anyway, we get the bill and all that was on this new card (mine, not my husband's) was that I had downloaded something called "Barnyard Girls." I am female and happily married and was in my 50's so we still joke about that one. When my husband called the credit card people they got ridiculous with, "how do you know the cardholder didn't buy this?" and my husband had to do an exaggerated, "because SHE (using my very female name) is my WIFE and our children are GROWN," etc. It took a couple tries for my husband to get the credit card cancelled, etc. he'd gotten it because it was a good rate or something. The incident didn't affect our credit history or anything.

There are no "police" on the Internet at all and buying/downloading porn and creating porn sites, etc. is, unfortunately, "legal." Every now and then the Federal government (US only so if you're in some other country you can do whatever you please since the Internet is not "owned" by any entity) cracks down using various laws but they don't work that hard at it especially if it's not child pornography. Local police would be useless because they have nothing to do with the Internet, there is no "local" about the Internet, it's galactic. There's no jurisdiction unless you're a US site and some US Federal agency wants to do something about it (FBI) but they only do something if it's hurting lots of people they won't do something about a "personal"/individual situation.
