1) Extension automatically puts random emails in signup forms on all websites 2) Emails will go straight to your messenger 3) Revoke access from those who start to spam you. Don't expose you real email address to spammers again.

Bot recently turned 1 year old, and has 3.3k users (which is not too much I guess). Privacy policy is clearly pro your anonymity and privacy, and I mean it.
PS. To those who know it, its basically a free version of ThrottleHQ.com PPS. Feedback welcome
