Post limit?

I've noticed that the newest House Yu isn't bumping with new comments anymore, and there are several new ones that. Is this a feature or something?

I believe it's 20 comments and no more bumping happens. It used to be lower, but that was increased. It's a bit of a loss, but has helped in keeping redundant bickering down.

Limit's been set at 20. I believe that's the maximum the danbooru engine allows anyways.
