You should know that it is not forbidden to sell BTT accounts
Well , no I did not know ! Actually I never thought it was a thing i would/could sell. I was browsing just the forum and I noticed this kind of activity in threads.
I was simply wondering what it was all about
Years ago account sales were not seen as something bad and during that time people use
Bitcointalk Account price estimator to check the account worth but the site is down now though.
After some abusive use of the forum with a lot of scam activities, different ideas were brought up which include account sales just to maintain the forum's reputation and quality.
