How can I purchase vip? And when purchasing vip is it permanent or is it like a monthly subscription?

Monthly subscription as far as i know, look at the "donate" tab

Edit: the donate tab is gone lol

If its VIP for sandbox, its permanent, and you can buy it here.

If its VIP for survival, its a 30 day subscription, and you can buy it here.

@No it's not atm, sorry.
