Certainly not. You can be assured of that! We have a try without sign-up just for the people who dont want to spend time in sign-ups / dont trust us enough. Its just that when we want to contact you for a genuine reason say send a mailer about a new template thats available we want that to reach you, specially since we spend on the emails being sent! And any list of such temporary emails are not enough to safegaurd us from this problem. But we will most surely re-think on how to solve this problem.

we have removed the restriction of popular email providers only. thank you for your feedback. its helping us get better! and also thank you for the list of temporary email providers, we used it to blacklist domains.
