for some reason, even having the maximum security settings, there is a chance these scammers can find you out. however, there is a really small chance you are hit with genuine ones. as a result, i'd have some advice below:

TLDR: most of these "investors" won't even prepare anything for any questions asked by users they are introduced to  . even so, doing any due diligence on their claims can easily figure out if they are even legit.

• if you receive a message which is already an introduction to their investments, lacking any disclaimers alone is already exposing themselves.
• however, if you receive the initial off-the-wall message from anyone you aren't even familiar with, check their profile and see who they are and how they even know you.
• if they tempt you to any investment and you have spare time to handle it, question their investment plans upfront with everything you want to know about. for example, where will your money go, the payouts, risks and benefits for participating, contact information, and more. even though it costs a much longer time than blocking, scammers expose themselves by not properly answering any of your questions.
• if they have any evidence of their successful "payouts", given that is a common red flag, beg them.
