I can only second your comment. I surely wish you get creative enough to make some spam proof variant of the Cropper. I really like the easy browsing through the list. Some ideas:
- Moderator approval: All avatars need to be approved by an moderator
- Anti-Spam question(s)/Captcha if you had problem with automatic abuse
- Make every user explicitely agree to not use copyright material/advertisement with possible warning/ban (like after 3 consecutive abuses)
- Probably already applied: Use your filter for banned websites.
Probably there are better ideas how to protect the cropper better from abuse.
Some questions remain for me:
Is there already a discussion about it ?
Is the cropper developed by you or an independent party ?
Kind regards
