When we want to create a selling thread on Link Sales forum, we need to add the domain and verify the ownership. And the first 3 characters of the domain name will be hidden. I think you should increase the number of hidden characters of the domain name from 3 into 5, because sometimes it is easy to predict the domain name. For example, when we are selling links on travel site with the domain name ***veleuropenow.com, it will be easy to predict that the first 3 characters is "tra".
