Mods have been doing this lately. There's been a lot of grumbling and discussion about transparency from Mod's and auto-admin actions, like show something that makes it obvious an admin action was taken or show the original title before the change somewhere.

Regarding titles specifically -- a change has the power to destroy a thread and drop it from the front page almost instantly.

Agree, and I noticed it as well. It is weird because sometimes these changes are so obviously dumb.
