Is it legal to sell character names?

[Toomuch]

So I realized that way back when (2010), on a second out that a rarely play, I created characters to "lock up" some names that I thought were pretty cool. However, I rarely play those characters. I kinda started in fall of 2010, quit a couple months later, then picked the game up again here in June 2017.

If someone else were to think the same names I have "locked up" are cool enough, is it OK to "sell" them the name (delete my character) for in-game pp or gear? I did do a tiny bit of looking around, and didn't see anything about this.

I guess I should also ask the question of if that could even work. Can one person delete a character, and someone else create that same character name? And if so, is it "legal" to sell the "rights" to that name? If it's not allowed, I 100% will not even try it (hence why I'm not posting any of the actual names yet).

Most of my cooler names are on Red, but still, I'm just curious. Is this a thing? If not, am I allowed to make it a thing?
