It doesn’t sound criminal too me. It sounds like one of those websites where they want you to click on something. Usually, people that are in experienced with those kinds of sites tend to fall into their little trap. They try to make easy money off someone. If that’s the case, it probably is civil more than anything. If they are doing something criminal, you will have to prove it. If you want to report it, take as much information as possible, printouts, web site addresses, etc. and go to your local PD and file a police report. They will then investigate into it further with another police agency where the criminal activity is taking place ONLY if they feel it is necessary--usually it never makes it that far. My best advice to you is to let it go and just stay away from those sites.
