So that explains the handful of random sign-ups I am getting on Communick. The pattern fits exactly what I am seeing as well (3-4 signups in an hour, weird usernames and gmail/hotmail addresses with lots of "." that are usually ignored. At least on my case the mitigation comes with my obsession in not collecting any unnecessary data. Email address are optional and only used if you are already a paying subscriber. Maybe I should just remove it from the sign-up form altogether and use it as a honeypot.
