a whitelist/blacklist should be managed by consensus, not one guy / exchange ( => corruption).
You're missing the point. If it were managed by consensus, how are the extortionists running this "Operation" going to get their money?
well, buyers of coins have leverage, too. I realize that few really care, but that really reflects on the structure of the forum at the moment. so anyone who comes up with a better model will be able to profit from that. the market will evolve, so that bad elements just get blocked. not that hard to do. so if 1000x bad coins exist, nobody really cares, because in the future everything will done on a neutral platform, and on that platform only reasonable candidates will exist.
