I would really suggest against flagging
- your rep is low
- your SP is going to be low after the delegation is over
People will retaliate, and unless you outgun them, it gets too messy
Moving on to the moral, not the practical, I would only police your own page for spam, not hunt it down all over Steemit
People really need to worry about themselves, their own page and their followers. Outside of that, it's out of their hands.
The fact that people feel it's their right to punish behavior, that is allowed on the platform seems a bit too righteous for me.
