Reading the table

“Available” comes only from a platform’s own sign-up check. “Likely free” means the platform’s own endpoint has no such account, which a reserved or held name can share. “Never” means the platform can prove a name taken but not unused. “By hand” platforms answer every automated request the same way, so Beat.rip checks their rules and links to the profile instead of guessing. Every platform gets the same rules check first, on your device.
