Changing custom avatar permissions - is it retroactive?

[induslady]

Hello,

I am thinking of introducing various usergroups with different levels of permissions/privileges.

Say, I have usergroup 1 - those users with less than 100 posts.
I am not going to give them custom avatar, custom profile picture or custom signature options.

I have another usergroup 2 - those users with more than 100 posts.
They will have custom avatar, custom profile picture or custom signature options.

When users in group 1 get promoted to group 2 on reaching 100+ posts, they automatically get these privileges.

Now, my issue is before I set up this usergroup promotions, I allowed all users to have custom options.

So few users already in usergroup 1 have setup custom avatar, signature and profile pictures.

How do I revoke those when I set up this promotion?

Please let me know. Thanks.
