Although buying/selling of accounts is not against the forum rules, it is frowned upon by most members here. If the bought account is discovered, it will most likely be red-tagged which renders the account useless. It's still better to work your way up.

Not sure did you read above what the guy says.
It is not against the rules but if you get caught you will be red tagged.
Which means no escrow will handle that kind of sale.
Which means it is always risk and there is no safe way to do this.
Which means build your own account instead of buying one...
