It didn't look like Scrap to me, unless it was a very good effort at hiding his posting style.
Scrap's suggestion that it was Duke Nukem (I remember him from AFF) seems likely to be correct. The style lines up.
The funniest thing I remember about Duke Nukem was when a very attractive young lady on AFF that Duke was being obnoxious and hostile towards, made a retort that went something like "I know more about XXXX because I have boobs". Duke's response was "I have boobs too". When it was pointed out that, as a male, he obviously didn't have boobs, he posted a shirtless selfie proving that he did, in fact, have boobs. Although I believe that the correct anatomical name for them is "moobs".
