Lack of membership has not been, for over 4 years, the problem here. I agree with this.
Seriously. Too many people. It isn't possible for everyone to get along, so I just have to keep trying what I think works best.
Anyhow, for my 2 cents, I just think there has been a general abandonment of standard law and order. I'm sure the powers that be will go after me on this for personal bias, but I think that SEN has steeply declined since Moose went ballistic and fired the entire Staff way-back-when. I don't even know where half the good Staff went (all right, some of the best like Beer and Clokr are retired), but, honestly, the administrative machine of SEN collapsed when Moose removed all the parts.
Sadly, to a large extent, I don't think it will ever be possible to rebuild a Staff of that caliber, and perhaps some of the retirements were inevitable anyway. v5 is lacking a lot of the bureaucratic processes, including meaningful ways of punishing people (nobody cares about minerals or post count on v5 and there isn't even a warn log). During my long tenure as senior Staff there were always graduated steps to take in punishing people, from warning to fining to suspension, and finally to IP-bans. These days there really is no meaningful punishment between a verbal reprimand and a ban, and so people skate freely.
I agree on the notion that there is actually too little bereaucracy and procedure in place. The major enforcement tool is still "banned or not banned" at this point. In a community with so many members and so much information exchange, it is ineffective. It works at a more managable place like Maplantis, but it cannot simply be scaled up and remain effective.
Also, since the Staff holocaust, SEN has been ruled by whim and decree. I don't want to be overcritical, but I think it is unprofessional to try to run a website of this size by choosing to ban members "when they exceed an admin's sense of humor".
Was that the reason? What happened to the "Unfortunately, he thought this meant I loved him and would let him get away with shit". This implies the aforementioned "shit" is the reason for banning.
Members like Kellimus and devilesk seem unbannable;
Devilesk appears to be slightly less of a dick than he was. Kellimus is banned. Devilesk also happens to contribute to the StarCraft community, whereas someone like JordanN did little, and Kellimus to my knowledge... did nothing. I'm more open to the idea of banning people who don't do anything productive.
(EDIT: I have to agree with MilleniumArmy, who wrote his post while I was writing mine.)
None.
