Ask yourself this question...
Did I ever log on to anyones BBS as a user? Before I started my own? Ever get in flame wars as a user? Ever have a group to help you fight those flame wars?
You apparently think it's amusing to try to "keep me guessing" where your vendetta originated, but it really isn't. It's disingenuous. How about just coming out and saying it, or is candidly saying what's on your mind not your style? Actually, I suspect that the fact is that this vendetta has a recently failed penny stock as its origin. It does seem to be what you focus on.
Pretty pathetic to imply that I somehow wronged you over 15 years ago and it only bugged you enough a year ago to start getting your vengeance for it.
So, what board was it you ran that I supposedly called more than 15 years ago to cause you grief? I'm especially curious since I only called local boards.
