Yeah, and it's called email@example.com
Seriously. You're doing the right thing, and it's the ONLY thing any of us have power to do. I've passed on your forum posts to people with more power, which promises nothing except maybe they'll read the email, maybe they won't.
But in the interests of not making a tense situation worse (you mentioned flamewars, I'm not ignorant of the past relationship issues here), I opted to close the topic rather than have people get in a huff.
Please don't open up more topics on this. I get that you're having a rough time, and I do wish I had a better answer than 'keep pegging the email that isn't responding' right now but I don't. Officially, THAT is the way to go about this. It's the only way I know of, unless you happen to have the emails of people on repo-staff who can help you out personally. Heck, if it were my own plugins, I'd be in the same boat as you!
(Please note there was recently an issue with the repo so you're probably NOT gonna get much help from them tonight: http://wordpress.org/news/2011/06/passwords-reset/ )
