I don't consider users "visible opponent users" however if you wish not to have content flagged simply ensure that the content in question by any kind of user is content that shouldn't be flagged. ie. original work, testimoy, valuable and desirable content and insight. it's that easy.
two user named @saywha and @illuminaughti are constantly flagging my posts because both users have rift with me on steemchat
I flagged you after you flagged every single post of mine lol. And you were making vulgar hateful posts about people myself included
