By ALL MEANS be skeptical and do research and DD... It is absolutely vital and encouraged around these parts (here in AMFE land)... Especially important in the OTC world... But like you said, raising a question for information to gain knowledge is different than repetitively raising the same questions and freaking out about everything without merit or reason, nor responding to those who try to help you out... That is just someone stirring trouble in my honest opinion...
I tend to give people the benefit of the doubt, but I am not so blind I that I don't note certain behaviors of each person...
It's like a game of poker sometimes around here... You got to learn who you can trust and cannot trust by subtitles through time...
