Specifically, for some reason this question on heliocentricitythis question on heliocentricity seems to invite a lot of views outside the realm of the modern science. One had been there for nearly a year, another appeared sometime within the last two days. I've noticed now that both answers have disappeared. At the time, I checked the help center and couldn't find any definitive reason to flag them, and just assumed an incorrect answers is still an answer, and it will naturally fall with downvotes.
Assuming they were deleted by moderators (or really quickly went through close reviews), should we be flagging answers like this? If so, what close reasons should we be presenting?
