the masternodes should vote on thread moderation and also who the mods could be. trolls will still bump the thread to the top but then they will be deleted unless they have legitimate questions. repeated instamine quotes is not a legitimate question.
I think our thread is fine, there will be trolling in any popular project, I would be worried if there was not. I don't think our official announcement thread should ever be moderated as we have nothing to hide. People that make it all the way into a crypto currency forum are smart people they should be able to judge the work we are doing and decide if they want to support the project or not.
Spamming the same thing over and over and over for months with multiple different accounts should be moderated.
