He tried to censor anyone that wanted to discuss BFL (bad or good), even went so far as to start deleting threads consisting of many pages of discussion. Remember when he moved all the threads to german off topic, then locked the only remaining BFL thread? He felt very strongly that it was a scam, and that discussion regarding BFL shouldn't be allowed or should be heavily moderated.
My post in the staff forum (before payments mind you, this was 6+ months ago).
I get Diablo doesn't like BFL and thinks it's a scam, and he's certainly free to express his opinion on that, but abusing his mod privileges in this way because of that is going a little too far.
05:39 < Diablo-D3> I fixed the problem.
This is the whole problem with it though.
05:36 < Diablo-D3> sipa: because bfl has basically admitted there are no units and never will be
05:40 < sipa> i asked for a link
05:41 < Diablo-D3> yes, and I said go find it yourself
05:41 < Diablo-D3> it might have gotten misplaced in the cleanup
If there's a chance you're moving information like that (that appears to have solidly convinced you it's a scam) to off topic over this, or "misplacing" it, perhaps you should reconsider the standards you've set.
This part in particular I still strongly believe "People are more than capable of making their own decisions without our interference", assuming they have access to all the information, and not just what some dude who happens to be a mod thinks they should have.
