I vote ban. (Raise your hand if you're surprised!)
Obviously I haven't been around long enough to have seen the Tomos oil-injector debate from the beginning, but I think targaped is at least partially responsible for the recent (ugly) debates about it. If he hadn't kept bringing it up, arguing the point, and turning it into a personal debate, I don't think it would have escalated as far as it did. I'm not trying to say that one side is right and one side is wrong (let's please not start all that again...), and I'm not trying to say that it doesn't take two to argue. I'm just saying that I think he added fuel to the fire and didn't try to put it out once it got started.
I know I'm not alone when I say that I am sick to death of reading his ridiculous posts. He makes paranoid accusations, spams the forums, and never misses an opportunity to continue to shove information about his trip down our throats. Is anyone else starting to twitch whenever they see "7500 mile" or "Canada"? I am. (Sorry to all the other Canadians out there. I don't think poorly of the rest of you.) 98% of his contributions to this site either piss people off, annoy people, or divide people. I don't think those are the kind of contributions we need more of.
To be fair, he's added a few helpful comments now and then. He's got his little tire tips, he's got his little "remove the whatever-it-is from your exhaust" and probably one or two other things. However, those tips are now archived on the site where anyone who wants to can look for them. It's not worth putting up with his crazy rantings, spam, and other bullshit just so he can occasionally offer a helpful tip.
So yeah, I vote ban.
