The best proof of his journey can (unfortunately) be found on the wiki.
I'm beginning to wonder if this isn't some sort of joke with him trying to see how riled up he can get us all. I mean, most people who have reached the level of crazy that he has apparently reached usually end up in a hospital, jail, or mental institution fairly quickly. Also, it's kind of convenient that, by changing his name over and over, it becomes nearly impossible to find all the posts authored by him. (Unless I'm missing some sort of way to search, but I've tried everything I can think of.)
I was searching earlier trying to get a better picture of everything he's written. I doubt I found even 10% of what he's posted, (a) because I can't remember his 300 name variants, and (b) Harold (thankfully) deleted a lot of them, but of the ones I've found, very few are actually helpful posts. Even when writes something that could be construed as "helpful" he includes a personal attack, a conspiracy theory, some sort of rancid pontification, or another of his ubiquitous references to his stupid journey. He has also personally attacked and libeled, vilified, or otherwise defamed probably 20 people at this point. I don't think any of us much care what he has to say about us, both because it's laughable and because we all know he's a crazy old coot, but it's getting old nonetheless.
I was under the impression that some of the main guidelines of this forum were that we should not post inflammatory statements and that we respect each other. I know those guidelines don't always get followed by everyone, but Targaped currently holds the #1 spot on the list of people who abuse that ideal.
If you guys want to give him a chance to change, whatever. Give him an ultimatum and attach consequences to it, though.
Maybe the accounts he currently has should be banned. If he really wants to change, he can create a new one and come back and prove that he's changed (much like Nate did). If he just wants to keep pulling the same old bullshit though, he deserves an IP ban, no questions asked.
