I totally agree with you, and while we do obviously have lives outside of Newschoolers, being a moderator is a commitment and it's something to be taken seriously.
That being said, I just don't think that scanning every single BST thread to see if it has pictures or not is a moderator's job.
We aren't the police, it's up to the members of this site to use BST at their own discretion.  If someone doesn't have pictures in their thread, you can either disregard it or ask them for pictures. It's that simple.
It's certainly not an issue of laziness and if it was a bigger problem, it would obviously be addressed and enforced.
