This is an excellent point!

I would probably prefer a client to show whatever nickname the user wants to go by, and have my alias for them shown less prominently next to or underneath it. This would be particularly useful for tagging them, if I can search by the alias I assigned. That said... I doubt I would ever take the time to assign an alias to everyone I am following, so I am not sure how much use this would get in practice.

I am divided on how a client ought to handle the pfp. I can see the value of having the option to not accept the updated pfp, particularly if they are clearly trying to impersonate someone else, but I also don't want to be spammed every time one of my followers updates their pfp with a request to accept or reject it.
