My question involves court procedures for the state of: California


I received a disturbing letter from the CEO of my ISP indicating they received a subpoena from "law enforcement" requesting the name associated to a specific IP address. My mind has not been at rest since I received this letter. I've been trying to think of anything at all that I could have done to warrant a subpoena, but I keep coming up with nothing substantial. I considered that maybe it was violating the TOS playing on Evony.com by using multiple accounts, but it doesn't make sense that they would subpoena my name for the IP address when they already have my name (via the many paypal payments I've made to them).

I have contacted my ISP to try and learn more about the subpoena, but they will not tell me who ordered the subpoena, nor provide a copy of the subpoena. They only informed me that "law enforcement" requested the name associated to my IP address, and that there was no reason given for the subpoena. They complied immediately, and wrote a letter to me to let me know that they complied.

What are the possible reasons for such a subpoena? Considering that I only know enough to stress me out, and not enough to actually do anything, I'm not sure what the point was in informing me.
