Yes. It is not against the rule so technically it is allowed but it is not encouraged as some people view buying and selling of accounts as dishonesty because some people use accounts to scam or atleast cheat. Most people I know buy and sell for business and also use it for sig campaigns.
I think a member is about 0.01 -0.015 btc
full member 0.03 - 0.06 btc
Sr. member is around 0.08 - 0.12 btc
hero member for 0.15- 0.2 btc
Legendary - 0.3 btc
these are just based in my opinion I don't know how much these accounts cost if you will ask someone. These prices are still affecte by the post quality, trust feedbacks, account history etc.

This is basically for people who are illegal aliens or fugitives from the law..haha
