I can't find any way this is done so i came here to ask.

Recently I was chatting with someone while not in any room. The other person received a message from someone unexpectedly so they changed their name to something similar and the person messaged again.

I know sometimes some clients may show someone as they change their name but is it possible to search for variations of a name? The messages finally stopped when my friend stopped having a variation of the root name
ie: Original name: Chatter

each variation got messaged until the name was completely changed. I'm not sure this is making sense, but i'm curious how that person was following each name change while not in any rooms.
