@heymtj If you have a better way to prevent Vivaldi WebMail from being used as a spam factory (thereby destroying the utility of the service), you are welcome to propose it.
The system to earn webmail has literally nothing at all to do with the popularity (or lack thereof) of a user's posts. (there are things like sync, blogging, participating in Vivaldi Social) that contribute to your earning webmail irrespective of whether anything you post in the forums will be construed as "negative" or "positive" feedback. There are users here who have earned webmail and whose input is almost purely negative. Practically all they do is complain, slag and insult Vivaldi and and point out how the devs are doing it wrong, everyone else is doing it better, yet here they are.
You can't get webmail instantly with a new user profile essentially because there's no way to prove it's you without management themselves violating Vivaldi's privacy policies.
Webmail at this point amounts to an insider perk. If a person can't be bothered to invest a few hours participating as a Vivaldi community member, yet they simply MUST have webmail, then they'll have to turn to one of the several free webmail offerings on the web - offerings from companies that are using user's webmail accounts to generate income, unlike Vivaldi, for whom providing webmail service is a pure economic loss.
