This is not really a grammar question; it falls into an area I call "tight writing." No one can slam a grammatical error tag on either one of your examples; the question is what that adds to the clarity of the sentence. It's quite clear [that?] it contributes nothing.
Some say [that] a majority of the THATs used in writing today can be eliminated without error or lack of clarity. This is such a case.
Yes, both are fine. And, as you pointed out, "that" adds emphasis for the listener or the reader. So, it really depends on if you want the clause to be emphasized or not. Hope that helps.
Both are grammatically correct, and equivalent. The one with the "that" is, I believe, more pleasant to the ear. However, the passive "It's imperative" is stilted and superfluous; the sentence would be better recast as "You must post...", which obviates any question about "that". But if you insist on a roundabout construction, be specific: say "regulations require THAT you post..." or "the contest rules require you TO post..." or some such.
