Sure serious amateurs can do serious science too. However, I have less reason to believe in their results, a priori, because the internet is full of cranks, while University Lab's have proportionally few. So a claim from a lab becomes an extraordinary claim from some rando on twitter, and thus the rando needs to provide extraordinary evidence.

That looks like a solid and defensible position to me.
