Topic: I think account selling should be allowed and even supported
If you have ever played long time running mmorpgs, you know why I think that. There is always some that leave and some that want to start playing. Unfortunatly a newbie often is discouraged because he has disadvantages since he is a newbie (less equip, gear, skill levels, what ever). After some time he will either decide to quit because of that or get along with it. The ones that quit could be kept if they are allowed to buy old accounts from quitters.
I see nothing bad about that.
If the dev team created some mechanics to trade chars on the website, there might even be some that buy another account laterwards to have a mining alt or sth like that. You would need to have the choice to change pilot name and start fresh in a starter corp in your biography.
Note: Having to start with a new char in a long running game like PO or EVE is a reason lots of people I know don't join playing later on.
