Well it's obvious that the selling and buying of bct account is still going on and this heinous crime is not looking to end soon. I see ads my individuals wanting to sell bitcoin talk account of ranks above Jr member.
In my own opinion buying a bitcoin talk account is more of a disadvantage to the buyer an existing member for some certain reasons(holidays, needs fund urgently, sick etc) might wish to sell there BCH account and a buyer gets it then when he or she decides to come back would head to meta with a new account and report it as stolen, hacked or so on(they have the bitcoin address signed message) then a rift would likely breakout which might leave the account in question with a negative trust tag.
There is no short cut to success you have to work for what ever you would get. Never engage in buying of bitcoin talk account work on your own personal bitcoin talk account and anyone wanting to sell account to you is obviously a criminal and it would be crazy to trust a criminal
What makes you think that someone selling account is a criminal? Maybe they are done with the forum and want to get any value out of it since there is some willing to buy it.
It happens in many places but even more on trading or market related forums. In most of the places it is not allowed to trade or use multiple accounts but it still happens. Over here staff made it clear that this does happen and they will not mask it to make you feel that it does not happen.
Is it right? Completely no. Clear indiaction of buying account might be associated with potential scam which can exploit trust of account gained by the previous owner. If it's not scam related then it will most likely be that user is trying to make money by doing bounty campaigns.
It is a pity because it significantly drops the value of account and it makes you lose the trust where you will question wether someone is a genuine or not.
