I remember running into 2 people who were obviously playing on characters they bought from bots before. They were both level 55, had the exact same jobs leveled, wearing the exact same mix of darklight and ironworks gear, and using yell in Limsa (not shout) to ask about how to join "a guild". When I asked one about the weird gear setup one of them just confusingly told me "this gear is supposed to be appropriate for our levels". They also said that they didn't know what a tell was and this was back before SE cracked down on RMT spam.

The whole thing was surreal and I'd really hate to imagine how they fared going straight into heavensward content when they didn't even understand the difference between basic chat functions.
