Were the names near identical and a bunch of gibberish? Then it was RMT, though i doubt it as RMT usually dont take the time to get to 50 an gear their jobs, unless they were maybe going to sell the accounts. Usually these days they just create a miner an bot-mine a low lv zone for shards. If the names were regular words, then most likely I would say dual-boxer, tho I dont know alot of dual-boxers who have identical jobs/characters goin on, an i'm a dual-boxer myself, i play my character an my wifes character all the time. Most likely, I would say the simplest solution is prolly the best one, so I would bet gil that it was just a coincedence. When zoning in from a tele people can spawn o top of eachother all the time, an its entirely possible that many of them could be wearing same gear. The reason I say this is because, it would be impossible to clone a character. Each character is registered to an account, and each character has a characterID, so logging in 2 of the same character would cause one to logout.
