Add a colored circle (red, orange, or green) to the Proxy field in IP Info. This should give users an idea what kind of proxies are problematic (red being most problematic, possibly requiring a block) and which are okay (green being ok, can be ignored).
The possible values of proxies and the colors they should show:
Red
- Tor exit node
- Hosting Provider
Orange
- Anonymous (what does this mean, aren't all IPs anonymous?)
- Anonymous VPN
- Public proxy
Green
- Corporate proxy (or legitimate proxy)
- Residential proxy
