I recently posted a question about the relationship between non-semantic and non-syntactic aspects of language, and logical functionality. An SE user proposed a number of grammatical and similar edits, at first entirely within reason, but after I provided an explanation for why the proposed edits were actually not justified, this user still went ahead and edited my post, as if they didn't pay any attention to my explanation at all. Moreover, this user is not even a moderator or significant contributor to the PhilosophySE in particular.
How can we ward off this kind of "outside interference"?
