Yes I have seen examples of this behavior too. It is tough at any point to start managing a community you are a part of and I think it should be no single users job - we all have a part in making STS succeed or fail.
Perhaps the moderation team, once finalized, will have some input here.
One thing I was wondering is that bearing in mind after day 4, a post cannot be upvoted and only downvoted, a level of value for a post can be assessed and the pending rewards adjusted to be more in line with what is considered fair for this content.
If you have any ideas on this feel free to post/tag me or respond here. Have a nice weekend :)
