Question related to sampling #47

Hi,

Thank you for providing such an interesting paper to read. I am confusing about the sample selection. The sample selection was based on Pinterest, while "a majority of elementary and secondary teachers turned to Pinterest". Will there exists a selection problem here?

Thanks.
