I’m quite sure that this is already the case, and the numbers are higher than 1%. Modern society has a lot of pitfalls which we are blaming on FB/Insta instead.

A similar example is when newspapers report on a high-profile suicide, and you have multiple copycat suicides occur afterwards. You wanna ban news reporting too?
