If a person deletes a character, there should be a delay before they can make a new one in that same account slot.

The higher level the character, the longer the delay before they can make a new one.

Level 1 character deletion should have a 1 hour cooldown before they can make a new character, a level 90-99 character being deleted should impose a 7 day cooldown in that slot.

Normal players do not delete level 99 characters, only rmt do.
