We are mCaptcha. We build kickass CAPTCHA systems that give (DDoS) attackers a run for their money. And we do all of this without tracking your users. Oh and did I mention our UX is great?

Survey link: https://survey.mcaptcha.org/survey/campaigns/b717e51e-24d4-4ab6-912f-de2dfe3ce1fe/about

NOTE: The survey(at least, the lucky draw is temporarily suspended due to some logistical reasons. Apologies for any inconvenience caused.

mCaptcha relies on a proof-of-work(PoW) mechanism to guard against bots. In order for this to be effective, the difficulty factor should be configured properly. If the difficulty factor is too high all the time, it will inconvenience the users and if it’s too low during attack, the defence will be weak.

So we are conducting a survey to gather performance benchmarks from various devices and browsers. The data collected from the survey will be made public, we believe it will guide sysadmins configure difficulty factor properly.

If you are interested in the lucky draw, please save the `submission ID` and the `proof` will be presented to you at the end of the survey.
