I don't really see why only people who paid are excluded and not members who have more than, let's say, 100 posts. I highly doubt someone with over 6000 posts and who's been here for almost three years like yourself would be a spambot. I don't think it would be all that hard to exclude everyone past a certain post count and/or time that they've been registered from this measure because checking to see whether such people are spambots seems pointless to me, worse than pointless in fact because it's irritating to those who must put up with it.
Of course they could've also not excluded people like us on purpose to make us join the PubClub....
Edit: Hahaha, got the captcha wrong at the first attempt.
It's only set up like this because the whole reason a Spambot is using this as a method for advertising is because it wants to avoid spending money. Plus, the plan you suggested isn't full-proof.
We have hundreds and hundreds of dormant accounts going as far back as 2007. Its very easy for someone to sign into their old account, attach a bot onto it and spam the forums. Even then, a hundred posts isn't hard to reach and the majority of posters have at least twice that amount.
In short, a smart person can find away to exploit your suggestions, but wouldn't ever plan on paying twenty bucks for a few extra hits on his website.
