Problem:
In a Phorge instance with open registration, some users create spam profiles with a custom, uploaded profile picture which depicts problematic content (advertisements, NSFW content, etc).

Steps to reproduce:

1. PHP 8.2.7, Phorge at d725ffaa7728bdbcd07870e9e8f4d244eb9dcf41
2. Have a Phorge instance in which anyone can register an account
3. As an average user, create a user account
4. As an average user, under "Edit Profile Picture", upload and set a custom profile picture which depicts NSFW content
5. As an administrator, disable the account of that average user

Actual outcome:
Profile Picture is greyed out but still displayed and entirely recognizable

Expected outcome:
Profile Picture should not be clearly displayed anymore
