Chose your battlefield
Because of the way the forum works ( yes I am a stinker ), it is actually quite easy to miss clues on the mobile version of the software ( see Notes )
On the Desktop version the title, and other clues, are more visible. It is still easily missed because the forum is a very active community.
Pranks
The Community Content section is full of photo manipulated items.
I do not see how a zero tolerance ban on manipulated graphics would help the community.
Moving pranks to the Community Content section, and labeling accordingly, I feel would be appropriate action.
