Have you noticed when things we have know for years are finally reported we aren't running around rubbing it in everyone's faces?
Its because your subconscious really doesn't want this evil to be true.
ITYS's are for the end.

It goes back to intent.
If our intent is to tell the truth and help others, than it is pure.
If we try to tell others in order to bolster our own ego, then it is ill intent.
Told you so in this case has to be with kindness and love, not as a weapon.
