You would be better off not broadcasting they are for sale, some people here frown upon it and maybe negative rep your accounts for this reason. It's unfortunate but a large portion of the market for buying these accounts is scammers who think they will make a higher return back. There are other monetary purposes for them like sig campaigns but it is trickery.
To add, on top of the signature campaigns they can also deceive people by setting up altcoin ICOs and because they have a certain rank, a hero rank for example there are many that will trust the user and send bitcoin and end up being scammed, the same for gambling ponzis' and so on.
