At this point I think I’ll leave those posts deleted. OP changed the post titles before deleting, then subsequently deleted their account and all comments, so the discussions in those posts are full of holes.

I only see Blaze in the modlog, and that user has been unbanned. If you are aware of other users that are somehow not in the modlog then let me know.

Yes, Blaze has been unbanned from the community.

Spoiler alert: the drain is just a straight pipe to a bucket below the counter.
