You're not paranoid, vasek. We really
are out to get you.
I checked your list of posts and the only forums in which we share interest is "Tips and Techniques". Of the threads that you have started in that group, there was only one that I read and that one was on using wood glues. Your questions and comments were answered and there was no need for additional comments from me.
There is no such thing as a blacklist. There is a banned list and that exists for those who consistently break the rules. Nobody has been banned strictly because of their opinion. Criticising RCU as you say you have done is not a bad thing as long as it is constructive criticism. Much of the criticism during the early stages of the new RCU did not appear to be intended as constructive but still the administrators listened and followed the will of the masses in most cases. In those cases that they did not, most people have become accustomed to the changes and now like them. I can't speak for the administrators but in my opinion, constructive criticism is always welcome.
