Well, it sounds like that first site published his address. If it was done in an attempt to harass him, he may in fact, have a case against them.
As for the second site’s mention, I don’t know if “his opponents” are involved in illegal activities or not. You know, it is usually the bad guy who tries to take out the good guy. I have no problems with the good guy taking that person on.
However, as I am not privy to the local dealings there, I can’t talk with certitude. That said, everything else I know about him I like and support.
If the information is publicly available then there’s nothing illegal about it although it is bush league to say the least. That does not grant them the right to go on a massive fact finding expedition or dig into people’s viewing habits though.
