Sometimes when a requested username contains some special characters (?) the AntiSpoof extension gives a nonsense result.
I've seen this happened at least few times.
And for the record, the requested username had nothing similar with the "username" mentioned by the extension below.
The chosen username is similar to existing usernames: ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !!, ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !", ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !$, ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !%, ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !&
Sometimes Antispoof shows strange propositions which don't correspond to the wanted username. Everytime it shows ! ! ! ! !-based propositions.
Example:
Jeffxxx is requesting a rename to 134235629345692348.
