The truth is avoiding scam is hard all this scammers can make things look very very real and anyone can fall victim,you can see a link that contain stuff that attract people just a click can let them have access to what they want and most of this things are free things and some people fall for it.
I have just one advice on how to avoid been scam avoid clicking on links especially on Facebook or telegram.
Once you have the mindset that nothing is free in the Internet it will be difficult for scammers to have advantage over you . But when one have already made up the mind that free things can be obtained from the Internet this will be a strategy for scammers to use in getting advantage of people. Just have in mind that nobody can give you free money in the Internet, nothing is earned for free, money can only be obtained by handwork and price payed for it. Scammers on Internet always want to make a offer that can seems catching to people, but when this is known to people it is always hard for scammers to succeed.
