Based on this page (https://exhentai.org/g/1470512/df421d6663/), I believe that avy417 (https://danbooru.donmai.us/posts?tags=avy417) and qavi (https://danbooru.donmai.us/posts?tags=qavi) are the same artist. I'm not entirely sure what to do with this info (should they be merged? what name is chosen? perhaps they just link to each other?) so thought I'd post it here so someone more knowledgeable about Danbooru's tagging system could take the appropriate measures. Thanks.
