Almost everyone who wishes to sell their account will use an alt account to do so.
Bullshit. That's just your mentality since you live in the world of alternate accounts.
I see many people selling accounts using their normal accounts, and no one is leaving them negative trust.
If people want to use a throw away account, it almost always means they are looking to scam and not have the negative trust affect their main account.
Do you know this because you have so much experience in the account selling market?
There are a number of very reputable users who trade (or have traded in the past) forum accounts, and most of them use a throwaway account to conduct business in the forum account market -- this is even true for a few people on DT level 1.
The vast majority of accounts that are used to buy or sell a forum account are very new accounts, and the people who use a "main" account to trade accounts are the minority.
Even you have left negative trust for people in the past because they sell accounts
I don't see anything suspicious about the OP using a new account to sell his higher level account.
