Blah, freedom of speech exists nowhere.
I suppose maybe you might have overacted, but it seems to me that (if I understand what you said) you acted fairly. It looks like you actually told them about the trojans/whatever, not just came onto the board and said "THERE'S A TROJAN ON MY COMPUTER YOU BASTARDS!!!!!!!!!!!!!!11111111111111111111111111111111111111111111", as most people do.
Even so, it's their board, and I know from experiences here that loads of people coming here and saying one thing without looking for similar posts is annoying, and has caused a ban or two. You're probably not gonna get back onto that board, not that you'd need to, and it's within their power to do that.
I remember when I first found out about the "spyware" in msgplus I got really annoyed... and of course, I overacted. I didn't start shouting and insulting and stuff, and in the end people cleared the issue up with me, and I found it was a simple misunderstanding, and I'm still here. So maybe they overacted more than you... and yes, I respect Patchou too... both for giving us this optional
sponsor (not spyware as I thought!
), and for putting up with my complaints... and the several hundred other complaints from more annoying people.
