Banned for buying and selling character

[CPG215]

That being said, OP still deserves a ban. Not for 'sniping' (unless otherwise proved), but for blackmailing (proved). Which, in fact, is a criminal offense.

Theft is also a criminal offense. If it's valued over a certain amount in the US then it can become grand larceny. A felony offense.
Then there's this thing called theft by deception. Which GMs call sharing. No support given in that case.

Again, choosing and picking which laws they want to enforce, which to bend, and which to ignore completely.

Sharing is defined by the GMs as giving another person access to your acct/items. Once your char is on EM, you just made it available to anyone with enough RP to purchase it. Sharing by definition.
