While I cannot know everything that transpired under the metaphorical iceberg during the time of the events aforementioned, I suspect that you're definitely overplaying your role in such. If I recall correctly, by the time that I joined DDO you'd already been permabanned. You sporadically created new accounts for various purposes, sometimes to troll and other times to debate. But airmax's policy, as far as I know, was to close any that you made once such came to his attention. I doubt you would've had any sort of clout with him (not to that extent, anyways), seeing as how his objective was to do away with you for good.
Having joined in October 2013, I can attest that I was never banned. Not even once. If I had two accounts open then he'd close one, but that was it. If you know my history, as you say, then you can attest to how amazing that is, going by how most sites are moderated. He did get irritated with me at times, but I do not recall him ever having said anything to me that, in my opinion, crossed a line. He has always conducted himself professionally to the extent that I have been able to observe. I don't know how he's treated you, but I can attest to my own experiences, of which I am recalling to the best of my ability. I value honesty, be it intellectual or otherwise.
As for Imabench (he's active here so I might not be able to voice everything fully), I can't deny that I did plenty to exacerbate the situation. If I recall, I was sort of the one who started it: first I made a thread putting him "on trial" and then I made an Alt that pretty much parodied him (or his username, at least). Before he did squat to me. Our last flare-up was two and a half years ago, but before that the only person besides airmax who I recall ever helping me deal with him was ESocialBookworm.
I don't know to what extent you are socially "awkward", but it's painfully obvious to everyone here that you have a difficult time getting along with people in general, so I would say that you and I are not far removed.
