Riot do you check things before posting to the client?

I have watched most of the Man At Arms videos you link because they are interesting but the thumbnail linked in the client has me so put off. The quality is so fucking bad and the sword looks nothing like the Yi's blade. The photoshopped Yi looks like it was done by a child. They cut out one of his goggles, the edges are rough and it looks so bad. I know Riot probably had no hand in any of it but can't they at least have standards? That thumbnail is garbage and Riot shouldn't have posted it to the client.
