An annonymous person banning people with impunity seems a bit draconian.
If you have complaints about anyone being banned, or any of the other Hub Leader activities you can contact Agoracom directly at: contactagora@agoracom.com.
If it weren't anonymous even fewer Hub Leaders would take the time to clean up the board. That being said, some are more zealous than others and we don't always get it right.
I welcome the discussion in a positive or negative light because I think it is important to test any negative assumptions to see if we can defeat them, in a sense. If we can't argue against the negative, in other words, then it might be correct! So far I think we're doing a pretty good job of thinking through negative consequences and keeping going, but it is important to hear what others think could go wrong sometimes.
I don't think we would all be here if all we were allowed to read were happy, upbeat commentary. Obvious bashing aside, we need to keep an open mind and stop making these discussions personal.
