Hi there.
First of all I do not know is this subject belongs to reputation thread. Correct me if I'm wrong so I can move it to appropriate thread. I was reading about the trust system and as I understood you must be s potential or real scammer to be tagged. Administrator theymos said that DT members can't tag anyone for something stupid. https://bitcointalk.org/index.php?topic=5050263.msg47119519#msg47119519 Well he was talking about merits but as I understoot that refers not only to merits but to all stupid tags in gemeral.

I saw a lot of of tags from DT members with feedbacks like "Idiot" "Mentally sick" "Shitty person" "Meritted a scammer" e.t.c. I checked that profiles and found nothing that was related to any type of scam. So my question is if it is allowed to tag a person just because you don't like him? Is it allowed to tag someone because of your vendetta or something? Also I would like to to know why obvious scam threads were not closed before they scammed out millions of dollars out of the gullible people's pockets?   

Bitconnect - Biggest ponzi in crypto history. Slole around $ 1biilion - the thread was not closed despite many warnings. After it's collapse many people left homeless and some of them commited a suicide.

Ethconnect - Obvious scam that just stole around $ 4 million and vanished without giving out a single token - The thread was closed by topic starter to avoid uncomfortable questions.

Bankera - Collected 140 million dollars via ICO. - After the listing and now the token cost and trading volume are almost zero. The thread was closed by topic starter to avoid uncomfortable questions.

Bitcoin gold - hard fork with a hidden 200 000 premine which was sold on exchanges within first days of listing for $150-200 that equals $ 40 millions. - The thread is open and alive. (Well here they did not steel anything but the people who bought BTC gold on early stages lost 80% of their investments)

There are so many more. Sorry but it will take a long time to name all of them. Generally speaking 99% of all ICO's was nothing but a scam.

I read that scams are not moderate because it is not our business. That is the statement of bitcointalk.  But I am sorry... 99% of potential private investors (not institutional ones) are coming here on this forum to find some crypto investment opportunities. Many of the do not understand how it really works. So closing the scam threads on early stages or forcing suspicious projects to escrow investments can save a lot of people a lot of money and maybe someone's life as well. Please let me know what do you think about this and sorry for my bad english (I'm Russian)
Thank you in advance.
