@...Mack:
Let me phrase my comment this way:
Person A: “Hey! Look at this cool tattoo I saw online!”
Person B: “Yeah. I saw it five years ago when it was posted on *Cutting Edge Body Mod Website*. Stop showing me stuff that I already know about.”
Person A: “Oh. Okay. Hey!- Person C- have you seen this tattoo?”
Person C: “No! That’s pretty *whatever the hell opinion they have*”

Now multiply that by a “room full” of people.
The “tattoo people” like you are the informed minority on the topic, but most of us still like to see these things because they are novel to us.
The scroll bar on the right works fine. I would sympathize with you on this if it were a theme day and nobody posted anything but shit you had already seen, but all you have to do is choose between ignoring the stuff that bores you, and informing people about the origins of the image or even telling them where they can go to be just as informed as you are.

And, please refrain from cruise control- it’s dumb.
