From includes/DefaultSettings.php:
/**
- If you enable this, every editor's IP address will be scanned for open HTTP
- proxies. *
- @warning Don't enable this. Many sysops will report "hostile TCP port scans"
- to your ISP and ask for your server to be shut down.
- You have been warned. */
As a feature that, according to its documentation, most wikis should not enable, and furthermore one that currently requires a deprecated, undocumented setting ($wgProxyKey) to use securely, does it really make sense to keep it in core MediaWiki?
Version: 1.22.0
