Unfortunately, I don't have the right to change my avatar as my current campaign have requirement of wearing avatar now. But I will try to give this an exposure by sharing this to my local.
Of course you are not wrong because the OP stated that in the beginning. But you can still use it in the private text area.
if your signature campaign requires you to use an avatar, you can just add "NotYourKeys.org" to your personal text area instead.
OP because I want to help pass it on for free, let me use it in my personal text space for a while. Hope this is good for all.
