Definitely sounds like a RMT seller/bot. It's a classic RMT-type name and they've been wreaking havoc on the Rakshasa/Onishi markets on multiple servers lately.

I have no idea how they're making items on a lv1 gladiator though. Last time they were crafting their items on one realm with craft bots, loading them on an alt, transferring the alt to a new server and unloading everything fast. Maybe they're name changing their actual crafters to avoid detection.

Enix will ban these guys, so do send a detailed report. The last 3-4 occurances were banned and vanished from the mb's entirely.

Also this is one reason I find the World Visit buying items on any realm baffling. They've got a nasty crafter RMT issue and they're basically giving them the entire datacentre as a market to find buyers.
