Fourth rule in uploading section is following: No low-quality edits (rotated, mirrored or picture-in-picture images).
How come all "picture-in-picture" from RaidyHD is allowed?
Example: [zmm95o]
This image has an good-ish anime character, and a purely shitty background. You can see pixels without zooming in.
The rule clearly states no low quality picture-in-picture The tag picture-in-picture have over 1600 tagged wps.
