i wasn't aware of that
They can really regulate all of that. They depend on us to be smart and use our common sense.
I believe the EP uses some sort of logic to determine if a flagged item deserves to be removed. Flags for things like death threats and jihads get elevated to the level of human attention and decisions are made rather quickly usually to remove the material. Flags for things like penis avatars get the automated response. Enough flagging and it gets removed, not enough, and it stays.
Because they lie.
If you post it in the Improve EP group along with links to the profiles, they will eventually get to it. Once it is part of public awareness, they move to get it taken care of.
It will be checked if you flag properly. These who are ding this are OLD dudes trying to grasp hold of an innocent. Just make sure you don't 'block' before you flag
