I've constantly been seeing people in different chats on different servers, asking for people who offer purchasing rankups for ingame items. I would be thinking that on different servers, you could earn up enough ingame money to get the cheapest rank you can buy with real money. My suggestion is that that maximum rank you could buy with ingame money is the minimum rank. Or possibly on the survival server, when your /ar check becomes something like 10 days you could be ranked up to VIP. I am only throwing this out because I know of a couple of players (GoodOriginalName) who want people to rank them up. This is only a suggestion, and to make it more plausible I would have to put more thought into it.
