An interesting question indeed. I'm sure someone could provide some technical data on it, however, from a !SLOTH perspective. You're name is tied into the block chain as your wallet address so changing it wouldn't be possible. Having some form of display names on different platforms could be an option though. It's probably a rather niche thing to need.

I've seen discussing on people wanting to separate the content they create over different accounts, this normally just leads to them making a new account for different content which is allowed. I guess that's the only way to keep your 'teaching' content separate from you're poopy mcburger face content.
