Mentions are also listed in the message metadata, in the allowed_mentions field, therefore it should be very easy for Discord to strip mentions of deleted users' IDs.
Although, messages that used to @mention the user don't have their UID mangled (since @mentions are really `<@userid>`), so it'd be easy to correlate someone @pinging a deleted user and that deleted user responding to the ping. Seems like fixing this would be pretty challenging (logistically and computationally) given you'd have to arbitrarily edit other peoples' messages.
