My question titled, http://meta.stackexchange.com/questions/259072/should-there-be-a-grace-period-before-you-can-down-vote-a-post, is receiving a tremendous amount of down-votes and comment criticism.

The thing is, I already understand that my question isn't so great. But every day, that question gathers more and more down-votes, and I keep losing reputation points.

I already understand that my question isn't so great, but I'm still accumulating more and more down-votes every day.

I don't want to keep losing reputation just because of a disliked question that's been there for a long time.

Is it possible to request my question to be locked? Locked questions can't be voted or commented on, although they're still accessible. I want other users to be able to view that question and its answers, but I don't want to keep on accumulating down-votes.
