@Yawa2020, do you know that once in the past it was quite normal to sell/buy BTT accounts? I think that sometime during 2015, a change was introduced where such practice became undesirable, but not prohibited. Then some members started tagging all the accounts that would be involved in such activities in any way, even if it was only about the intention to buy/sell, without it actually happening.
there was even a service for calculating the value of forum profiles

now I can't even remember the last time a serious case happened, where a high-ranked and active account was sold. it is obvious that the current method still gives some results.
