This and post #2281693 have been flagged as duplicates. I'm to groggy to find where it's written at the moment, but this hasn't been a valid flagging reason in the past. Also, these images are not actually duplicates; they're PNGs from Pixiv that are replacing JPEGs from Twitter which are known to be compressed, generally pretty terribly. That said, neither of these images meet my personal standard for approval in the first place, thus this comment instead of just pooshing the butan.
