i know an example when a person gave flags to ALL posts of a man just because she was offended by him (as she thoight) and her SP was much greater than his and you can imagine what it was...(
flags are used to feel power and make quarrels, the reason you gave in the post are unknown to them as far as I see...
it's a pity people dont respect the rules of the platform where they try to have bussiness or friendship
