I'm so glad you are proposing this strategy, I was thinking of the same thing! It has an upside and a downside.
Upside: you link straight to where you want to be, the profile
Downside: it will be near impossible just by clicking the link to find the proof for manual verification
I want to believe that the downside is mitigated because, well, that's what Keyoxide is for! But as you mentioned, Keyoxide will show a link to the actual proof for manual verification. If you are a hardcore user that skips Keyoxide's UI, well then you probably have the knowledge to figure out that the
?proof= parameter represents the public group with the proof.
I think I prefer this
Goldstein I’d also like to note that the channel/group usernames, just like, ehm, user usernames are mutable.
True, hadn't considered that. But let's face it, you really have to try and sabotage yourself to change the name of the proof group. If one wants to, great! Their responsibility to update their claim. The documentation will state what happens in such cases.
