Our avatars are based on your Twitch avatar. Currently the sync is broken so if you change it on Twitch, it will appear broken here. We are working on it!
The best thing you can do is to submit your project and let moderation handle it :) If any rules are broken, they will let you know :D
This issue should be resolved now :)
Please submit a support ticket to us so we can help get this taken care of for you! :D http://bit.ly/CurseForgeSupport
