So, since there is a bit of ambiguity as to the circumstances surrounding my ban from the forum, I'll provide some background.
I originally joined INTPc back in 2006 or sometime around then; I posted for a while and then disappeared for a couple of years. I returned about the time Alyssa, a former girlfriend of mine, was killed in a car accident. At the time, I was going through some other things also, and spent a lot of time indoors on my computer. The forum provided a way to interact with others, express myself, whatever, without having to go outside and face the world.
I absolutely love to debate, but I have little tolerance for personal attacks. As a consequence, I will tend to respond to such with either feigned ignorance or some other absurd farce. Personal attacks seem to be all too common in forum interaction, and INTPc was not an exception to that rule. As a consequence, I was often prone to posting silly nonsense as a way to toy with these distasteful (to me anyways) posts. This, of course, is very akin to trolling since both aim to "mess with others." I eventually went so far as to create a thread entitled Are some INTPs Poopy?, after having met with so many "poopy responses." While I realize this isn't the best way to respond, and would now perhaps ignore rather than confront with the absurd, at the time I just felt like fighting nonsense with nonsense. -> "You post a stupid and ignorant response to one of my posts or another person's post, I'll respond to yours with absurd gibberish."
In parallel with this, I developed a reputation for being a creeper and stalker. There was a single member about which I made several flirtatious posts (Ironically only after she made one directed towards me), which created an environment of discomfort for her. There was absolutely nothing obscene or overtly threatening about them (As an example, there was a thread where we were using the South Park Character generator to create South Park versions of ourselves. Right below her post, I posted an image of two South Park characters: her character cropped from her creation, and mine, hand in hand). To me, this seemed like innocent fun, but I failed to understand that the internet is a dark and sometimes scary place, especially for women. For her, these were unwelcome and distasteful interactions, so she sent me a PM about her displeasure, asking me to cease and desist. I then made the mistake of not treating her feelings as valid concerns, and made light of them by returning her PM with a quote from an earlier message we'd exchanged (back in 2006) saying "she'd changed." In retrospect, I should have had more sympathy for her feelings of discomfort, rather than making light of them.
So, these two things culminated in me getting confined to purgatory. Momentum started building against me when a thread was created with a poll, asking whether or not I was a "troll or tryhard." Things snowballed until I eventually created a second account (not to circumvent a ban, but to also post in purgatory, for some fun), after which I was banned. The interesting thing is that, per the FAQs on that site at that time, this was not deemed a bannable offense.
After that permanent ban, I made several other accounts so that I could continue participating in the forum. Had the ban been less than permanent, forever, never to be lifted, etc, I would have probably respected it and not attempted to create other accounts. But, why do that when I'm never going to be allowed back anyways?
