I start selling all kinds of social media here !! and because the way of the delivery and payment i got 4- Trust from people who hasn't even try our service !!!
Its prohibited to do buy and sell of accounts. Well technically its not but its preventing everyone to do this, so your account might compromise in doing so. Better to have to do it outside this forum if thats really your business however those you sell accounts might be at risk of being banned or having negative trust knowing it came from a buy and sell which isnt practice here.
