I remember some time ago when you left a comment on Budz' vid just saying "awful". This wasn't meant as constructive critcism, was it? I mean that was just disrepectful...
I don't know you well enough to judge you on your general criticising methods, but if they usually look like that i don't wonder why you got banned.
In most cases it's a good idea to show some respect before starting to criticise. If you had replied to Knnth "ok first of all your style sucks..." I don't think he would have appreciated your feedback.
On the other hand, if you had criticised all the people the way you criticised Knnth, you wouldn't have gotten a ban anywhere. Or is that the case?
