what's preventing you to pull a JD and just suddenly stop operations
You make it sound like JD did something bad.
In other news, it appears that after I block people they can still talk, because blocking is only enforced in their own browser. They also seem to be able to appear like mods themselves, and issue arbitrary text in green, such as appears when people change usernames.
All this stuff should be server-side, not client-side!
Edit: a picture is worth a thousand words...
