I was talking my favorite sys admin at work about spam just the other day, and he recommends NOT submitting your email through any spammer's opt out form. All that does is tell them that you took the time to scan through the email to find the opt out link, and therefore, they will probably just send you more junk and sell your email address to more third parties. Spam is one of my least favorite things in the world, and I get tons of it daily (my AK account, which I have never given out, is essentially a spam repository, and my Hotmail account is utterly ridiculous), but I'm afraid that there's not a hell of a lot that we can do about it short of blocking all incoming email unless it is from specified people. Fortunately, there are organizations out there trying to stop spam (like SpamCop), but it seems as though it may be a lost cause.
