@MojangSupport Currently setting up my Java account and trying to use a username that all name sites like NameMC mark is as available, but when I try to use it I get that the username already exist. Please help

The recent removal of our API means that third-party services that have been using the API will no longer have up-to-date access to Java profile name histories. It's possible that a name may have since been claimed or is on an account that is not recorded on these sites. -JL

Is there anyway you guys could check that for me? Because i know Mojang sometimes block certain names by accident.
