Five years ago I ran a popular underground security forum. We never hosted anything like CCs but we did discuss and release (not sell) exploits, malware and viruses and we talked about hacking, including hardware hacking.
About a year after starting the forum up I began to notice some interesting anomalies in the log files. Not a week later and I began to notice that I was under surveillance. If you know what to look for it's not particularly difficult to tell. New vehicles appear in your area, acting suspiciously, your internet connection slows etc. I'm hesitant to go into the details but I immediately shut down the forum and the suspicious activity stopped.
Unfortunately there is no way to be sure whether I was simply being paranoid or whether myself and my site were being spied on, I have evidence but non of it conclusive. Anyway just a warning that you can have the best security measures possible and you will still get spied on if somebody with enough money, finds a good reason to spy on you.
