After a certain number of users is exceeded, avatars kind of become useless, nobody wants to look at 1500+ avatars.
My question here would be… what are you trying to achieve?
Are you just wanting to confirm that a particular user has accepted the policy?
If so, maybe just show the first 50 or so avatars + add a button that renders a modal where you can search for a certain user’s status.
Are you trying to get a gauge on the percentage of users that have accepted the policy? If so, the plugin could potentially display a progress bar based on how many members in the group have accepted the policy.
