DragonBee, that's their username in game. They're using a client. Let me do my thing and search for it.
Alright this is what I've gathered: He's from Czech, has a WOF pfp (I think? Honestly I don't really know) and his acc was created two days ago. If he just joined, and already knows how to hack and has experience in BB, he's probably has alts. It could also be the case he's using an alt to cover up his actions and hiding his main.
