Choosing difficulty factors that work for everyone is a hard task +because it isn't possible to accurately predict the kind of visitors +have. But what if had a system that will improve [mCaptcha +installations](/docs/introduction/installing-captcha/) +based on performance of it users? Enter mCaptcha net! + +The admins of mCaptcha instances can choose to upload truly anonymous +Proof-of-Work (PoW) statistics to +[mCaptcha/survey](https://git.batsense.net/mCaptcha/survey) instances, +which other mCaptcha instances can then use to automatically optimize +the installations that they hsot. + +NOTE: This system is opt-in, webmasters must consent to publishing +for the performance statistics from their mCaptcha installation to be +uploaded. + +## Ensuring anonymity + +mCaptcha doesn't fingerprint its users.
