Well I can help you out about the source of my avatar's. ( I got several created, yes created). Mangadex limits avatars to 1mb. So full animations from 15+mb must be created/cut/reduced to 1mb. Using extraction, combine and online reduction websites it's possible to get good stuff. The only problem is the site I got sources from removed a lot of content or lost it. I got sources no longer listed on the site. My presently using avatar is one of them, in fact all my created avatars are not list anymore. If you want to see whats left go to the site below:

I think devianart has adult restrictions on for the user. You may have to join and prove age to get there. There is no search forum features on mangadex. If there was you would have found a message like this one before. I have said it in the pass messages.
