Several questions, if you change your join date to 2006-2007, will you get + ingame?

Is it possible to change join date to future, in example, 1 Jan 2020?

What restrictions are on namechanges? (Maximum letter amount, also special characters, in example - and _)

Is it possible to buy animated 150x200x avatar?

Custom profile infraction, is everything in it possible?

If you have bought namechange in past, if you now buy namechange here, will it still be 25$ or 50$?
