however not everybody who is sending a message is automatically a scammer, so it is better to study by the actions and never to share any information.imparting the basics of wallets security is so much important before investing money can save someone from losing their own funds.
You're right but whether they're scammers or not, never share any personal information or anything wallet related especially if they private chat you without you asking for their help. If you publish a thread seeking for help, anyone with useful information to assist you will genuinely post under your thread. There's no need for them to chat you secretly unless they have other motives. I will advise newbies to treat every unsolicited pm as a scam in order to be on the safe side.
Always give less information or refrain from giving critical information to other people specially if you dont know who are you talking to, if you just meet them , be careful on dealing with this people , because sooner or later theybwill try to trick you, on giving or asking sensitive info.
It is a red flag when you need direction and ask a question on a board in the forum and someone chooses to reply you privately, since you didn't send them a private message they don't have to reply you privately even if the person doesn't want to scam you. If your question is in the open then you should accept every answers in the open, even if you reveal some personal information that is sensitive a concerned forum member will correct you publicly, if your comment needs to be deleted I'm sure that you'd be told publicly. Aside from forums like this you also have to be careful about receiving DM on social media, scammers targets newbies those platforms especially telegram, I still get a lot of scam messages with phishing links, I just ignore them.
