well here's one from me I learned the hard way... links from brand new posters are way more likely to have like 3 blurry pictures of nothing much... Checking to see if anyone has liked a post can be a good indicator of quality sometimes
It would be good if the forum rules required that each submission specify total file size, number of vids, number of pics etc. That way users have a rough idea what they are getting before they unlock the links.
