Good for you in venturing out into the scary world of Internet dating. Actually it's not bad at all as long as you understand the rules. I had subscribed to Match.com a couple of years ago and had a lot of good dates, but also I turned down at least twice as many through my qualification process.
In reading your profile I can tell that you have a good idea how the game is played. There are a few things that I would change just because I was very specific in what I was looking for. Just consider my suggestions and if they make sense to you great!
First off, you obviously get the premise of creating an attention getting heading. Consider this though, only tech heads will appreciate your particular heading while everyone else will either be frightened away or question your sense of humor.
Next, the c/f line about child porn is funny but it may alienate you from many women who would joke about that as much as they would about rape. Couple that with your heading about virus' and you may be considered an insensitive geek.
As for your date preferences, consider dropping the income hieght and relationship preferences. They will limit your field by making you seem overly superficial. Notice that I didn't denounce weight, I think highly of people who take care of their physical condition in this day and age. That is something a person can control moreso than their height, income and previous relationships. Also consider mentioning in your ad that you are attracted to women who agree that having a fit and trim body and lifestyle is very attractive.
Consider setting the focus of your first paragraph solely on you. Be sure you use a positive light, there are a couple instances where you seem to come off as a cave dwelling loner who doesn't think that he has a chance of meeting a normal woman online. Also, stay away from the clichés. Consider sharing some of the activities that you have done in the last couple of weeks.
Your second paragraph starts off with another sentence that makes you sound like you are a bit bitter. Try considering how it would sound in a woman's profile if she said that she isn't looking for a Neanderthal bonehead that only watches pro wrestling on TV? Wouldn't she sound as if she has had a previous bad experience that she hasn't moved beyond?
Overall, your idea of posting a pre-screening profile is a very good one, it's not one widely used. I'd focus on more of the positive traits that you are looking for and saying that you could be interested in someone scoring at least a certain number. Also, no need to remind them to be honest about their score, it just seems as if you are someone who had been lied to often in the past. However, you can use c/f in asking them if they told the truth when you meet them.
These suggestion may or may not make sense but you can't blame a guy who is majoring in the psychology of relationships in school. Let me know if you want more incite into the rules of the game. By the way if you are wondering, my gf found ME via my online personal and we've been together over a year.
