This forced board war conflict is cringe and gay, and anyone pushing it is a fat faggot with bitch tits nearly as big as squealer's. The sites exist for different purposes with different ethos, and that's how it should be. Anyways, on to the main 5 theories for SWATters:
1): Patrick himself, including him hiring someone to do it for him
One of the more compelling ones, as Fat is really the only person with anything to gain from this. Whether or not he's behind it, he's clearly trying to milk it for all it's worth, but the one issue is that Fatrick is a clinically retarded and morbidly obese 1.2 gpa failure, and I just don't see him doing it this many times with no issue, when he can't manage simple graffiti on his property once without giving up the game. Still, hard to ignore how convenient some of them have been, and how they amp up in frequency whenever Fat is trying to distract people or gain notoriety.
2): Kiwi
Obviously the one I most hope isn't the case, but it's hard to completely discount rogue actors. We get plenty of people in the thread right here from time to time a-logging and demanding we ween harder, and while it's far from the majority opinion or overall spirit of the site, it's at least worth considering. Generally though, when people a-log or ween, they're desperate for attention, so it's a little odd for it to be one of them when no one has gone on some ill advised attentionwhore spergfest trying to proclaim themselves as the "final boss of Pork Squealer!"
3): Pest
Easy to point fingers, given the different culture of their site, more personal beef with him, and the fact that 99% of actual contact with Fat comes from their end, but I feel like arbitrarily pointing fingers at them is just as gay as them doing it to us. My point above counts for double, pests love to post any interactions they have with him, from random tweets, to texts, and even phone calls. If attention is what the SWATter is after, they'd get plenty of it over at OnA if they bragged that they were the one doing it.
4): Someone he annoyed irl (Drunks at Hoolies)
Bit of a wildcard one, but from everything we've seen, Fatrick acts just as smug and arrogant irl as he does online, if not more so because a twitter post or text doesn't inherently convey his sanctimonious and self important whine that his voice always has. I could see him spouting off on how he's such an Übermensch for having a half dozen failed books and so much above all these dumb hicks at the bar and how sitting in his favorite stool is a hate crime one too many times. Vindictive alcoholics with nothing to lose can go to some crazy lengths to fuck someone over.
5): Someone he annoyed online (twitter)
I'll be honest, I'm just not seeing this one. The vast majority of his interactions come through twitter, and most of them are borderline incapable of doing the work required to find his easily accessed address. As someone else pointed out, they don't really seem the SWATting type, they'd just bot your tweet and brag about "muh ratio" until the end of time.
Bonus):
Crackpot theory, but what if it's someone with a beef against the farms, OnA, and any other sort of site like this? Obviously, we're the first suspects when anything like this happens, and it really ramped up when there was this massive SWATting campaign last year that perfectly coincided with drop kiwi farms. No one else really has much to gain from SWATting this fat retard.
