It helps to stop troll-flood all over the place, but it is also very inconvenient if you are in Bitcoin for few years, and still have to go through it :-)

It’s all about definition of scam.
If you understand scam as take other people money and run, then they are not a scam.
But if you believe that scam is also when someone deludes other people that he will deliver something on certain conditions, knowing that it is not possible from the beginning, then they are a scam.
They will finally deliver, but it is far from what they promised.
