I have lost around 800 reputation over time on Space.SE in lost bounties because I missed the dead-line to award it. I think the bulk of it may have been lost during a suspension, does that effect bounties?
It had a 500 rep bounty placed on 09-Feb-2019 and no one got it.
Side question: I read somewhere on SE, more features were given to moderators a couple weeks ago. Does the moderator have any control over bounties?
