I think most people realize that on a free form internet board there are no "requirement" to do anything.
People with literal minds that tend towards the authoritarian might insist on a riot of rules and insist that a poster MUST conform to the original posters REQUIREMENTS.
I see no requirement. I see requests.
I look at people like that and smile with a bit of condescending pity at the small minds of the authoritarian types who insist others follow their imaginary rules.
