Almost ..... almost every time some whale or big account has downvoted /flaged a post or comment is when they have done something wrong. Sometimes it is only a simple mistake, sometimes the WRONG is doing spam, or posting plagiarized information, etc.
I have seen a few Steemians whine or cry about being flagged or downvote... but for the minnow, I haven't seen it happen when they did nothing wrong. I haven't seen that yet.
Ok then.
I only responded based on what i have seen myself
