Deleted Posts in Pools

One thing I've noticed is that deleted posts still remain in pools, and there is no way to remove them. Does this have any impact on the server and is there any way this can be fixed if it does?

This is a feature, and has negligible impact on the server. We also don't delete pools with only deleted images in them.

There actually is a way to remove them: add the tag "-pool:###" to the post, substituting the pool number for ###.

I wouldn't remove them unless the deleted images shouldn't actually be in the pool, however. Especially since they can be looked up via a "pool:### status:deleted" search.
