Came home this afternoon to a rather threatening message from my ISP (Comcast) stating that I had violated their acceptable use policy by allegedly trading something copyrighted on K-Lite. According to the message, the Business Software Alliance alleged that I was trading a copyrighted file over the network. Listed a file name, my K-Lite username, my WAN IP, and the alleged port. (1214 though I actually run K-Lite on another port?!
My big question is, after using K-Lite for more than 6 months and keeping my machine on basically 24/7 with 8 upload slots, why is this happening to me now? Especially since K-Lite 2.4 now has the Peer Guardian list of blocked IPs (which includes the BSA) and I have checked "User's can't get a list of your shared files" which I thought would give me an added level of protection (though I'm aware PG list is not perfect.)
I should note a couple of other recent changes in my use:
1) I was on ATT which fully switched to comcast at the beginning of this month.
2) I recently started using KaNAT (because I'm behind a router) which propogates my WAN IP rather than my LAN IP. I am concerned about this because I worry it has made me more "identifiable". Also, to use KaNAT you have to "uncheck" "Don't save local IP's in DAT files" in the K-Lite options menu. Could this have made me more vulnerable?
Does anyone who has been through this have suggetsions about how to handle this with the ISP?
Anyone with more knowledge than I about K-Lite (or perhaps KaNAT) have suggestions about how to protect myself in the future?
I want to play nice and share but I can't lose my ISP over this....
