No need to get up in arms guys. Just throw it away. It's not like they have your SSN or credit card numbers. The mail you received has a name printed on it. Call them and ask how they got it.
Not up in arms really, and I do love the magazine, I read it back to back every time I get it... The sad thing is that unfortunately out of the lot of scam "renewal notices" they mail, some people will fall for it, that is why the keep doing it, I mean, the cost of materials and postage for thousands of pieces of mail via snail mail has got to add up, and if like you say, they been doing it for a good while, chances are is because it is effective, meaning that it yields the scammers a profit from unsuspecting subscribers, that is the sad truth...
It seems that an sticky at this forum describing the situation or even a comment in the magazine itself warning subscribers would not be too much to ask and it would be a welcome gesture, I mean, it is a magazine that many times publishes articles in spyware, and keeping your computers safe and other related safety issues, and now when a third party is using the magazines name and its subscribers database to scam and not a word about it it anywhere?
I am not up in arms, I am simply awaiting for some action from Maximum PC, it is the right thing to do.
On another quick note, I would not call this people from my home phone or cell, why? simple, they are scammers and I would simply be providing them with my home phone via Caller ID so they can ring me later with unsolicited telemarketing. You could try calling if you have an anonymous feature in your phone, otherwise, nobody should...
