The act of trading BitcoinTalk accounts is frowned upon by the community. Accounts are bought mainly for the use of scams.
Use your current account and build it up from the ground like most of us here.
Good luck.
You are wrong I think. Most of the accounts get bouht for using it in a signature campaign.
I think only DT2 users gets bought to scam, ofcourse some smaller accounts can be bought for scamming too.
However everyone can scam, even the trusted people on here, there are lots of examples that a DT account has scammed. So always use escrow(even the escrows can be scammers too).
