Apples and oranges. So you mixed everything you could mix and created really weird thread.
On the subject of coin mixing projects I saw split sentences, because it can be done and not everyone who uses it is criminals. Does not matter.. or matter..
You shouldn't drive car because criminals use roads.
Don't use banks either because criminals have bank accounts.
Also, rumor has it that criminals use internet so better go offline.
Don't eat, criminals use dirty money to buy food, it is best to stay away from all stores. Grow your own food!
When I figure out what other things criminals do, or, use, I will let you know.
then why something that is tolerated by forum rules
It is tolerated probably because no one can really stop account trades. There was also something about "moderating something will lead to false sense of security" but I will have to double check this.
is marked as a scam
Imagine trusted escrow sells their account. Would you consider that worth of tag? I mean, what can possible go wrong, account ends up in scammer's hands and easily pulls large scam. Would you consider that escrow person trustworthy? Or someone sells high ranked account to scammer and they do "exit loan scam". Or someone buys accounts and abuse everything they can (campaigns, merit, spam, shills for projects, bump...). Or someone sells DT account and they scam people who trusted original owner. Would you consider seller trustworthy in this case?
Or someone sells hacked account, administration maybe ban account which is scamming buyer then. It is just shady as it can be, that's why.
Not saying that all account buyers will scam/abuse, but why not sending neutral trust to accounts to make users aware that account changed owner or will change owner? Oh, probably because no one will buy account then(read above).
