I have been informed that it's against the rules to transfer social media accounts with the sale of a website on Digital Point. However, when you create your listing - one of the pre-populated questions is: Does this site come with any social media accounts? This implies that it's perfectly acceptable to transfer social media accounts with the sale of the site. This should be removed to help decrease the number of "rule breakers" in the sites marketplace.
That thread is correct. You can't sell accounts on this site. If you give a social media account with a business you are selling, that's different. If you create a website for purposes of giving a social media account, it would lead to you being banned. For example if the social media account is older than the site it's for, it's probably not legit.
