No, it means that the forum cannot effectively protect you from scams so you should learn to protect yourself proactively and not believe that there is a security cover which protects you from scammers, just like with Bitcoin.
I don't agree entirely with the idea and feel that a little more strictness on proven scammers and scam posts will help, but it's my personal opinion.
I agree with you on this point, it is true that protection from scammers lies primarily with members themselves by doing their own research and following safety rules, but there should be more strict measures against scammers in the forum.
Strict measures may help reduce these incidents somewhat, although fraud cannot be completely prevented because fraudsters will return with new accounts, new names, and new methods, so it is very difficult to control these matters.
