If we implement your idea, noone will be able to comment on "flat theory" posts because noone will be able to pass the test, who in his right mind would spent countless hours reading and watching BS? Those posts would stay unchallenged and people would actually think that they are truth, noone said anything against them afterall.... right?

To say it in another way, would a scientist spent more of his time reading nonsense to pass a silly test in order to be able to comment on something that is fundamentally wrong?

Again, do this test for yourself, go to my "spam/irrelevant/unrelated" link about flat earth theory and check how much you are able to read and watch in order to pass a "test" so that you can comment on that post.
