I have seen certain profiles who are in war with others and get flagged only because of that. May be the war would have started sometimes back, and has reached to a level where each party is not willing to leave the ego because of the position they are in.
In general, its not good to cross paths with those angry people as you mentioned. No common solution , just a good common sense is all that needed.
It's almost sad. I've felt that kind of hate too so I know why it happens. But a flag war can't and shouldn't be the solution.
Maybe we need a steemit-mediation team that tries to solve fights like that.
They say, if you just put their name in your post, you get flagged by their enemies. It has gone to such a level. I don't want to even spell their name here because of that 💔
Search for a profile with reputation -19, if you can.
-19? That's extreme! And I didn't name any people on purpose as it's a problem with the whole system and there will always be new people to abuse it.
