Greasy Fork

Quiet a long time I haven't logged in GreasyFork.
I'm not sure if I just missed some update of this site (maybe this year, or maybe even earlier).
I just noticed my username was renamed by adding a " 3" after it.
So... Could anyone point me a post about what happened?

O-Okay...
But... does this means there are 4 users using this user name (with differ only by capitalization) before renaming?
So they can be renamed as "ts", "ts 1", "ts 2" and "ts 3".
You know, there are at most 4 possible combination yet...
