Listing scammers is a whack-a-mole approach and sadly most people scammed are the newbies to crypto who don't even know of this forum. Not to say something shouldn't be tried, but the suggestion to educate users may have better long term consequences. Also the negative trust system does label posts strongly to be careful so there is a basic system in place.
Look at the recent PlusToken scam, it ended up touching up to 1% of all bitcoin which is a huge scam. However the millions of people scammed were new to crypto, mostly talking into it via wechat, and were walked through how to buy in. Unfortunately nothing done on this site would have helped those hit by PlusToken.
