Vivaldi is not at fault. It is the users who should review their usage. As long as you are still part of an organization, or keep your own little piece of internet alive, there is no reason to prevent delivery of messages to your address. Just like with mail in the real world, if you can be found at a public location, mail can be delivered to you there. There is only jail and army to filter your mail. The free-of-charge nature of these services is just a reward for your membership in an organization, there is nothing permanent or guarantee here. To the people who want a free-of-charge address, find a public service or a respectable association that at least guarantees reception. If not, keep a low profile, you are under voluntary surveillance. Services like Vivaldi or Gmail and consort have the worst level of freedom, out of 6 levels : 1. My domain / My server / My IP - Freedom. They can just list you on antispam service if you manage badly. 2. My domain / My server / My ISP IP - Freedom but nomadic. Your ISP can cut off the relevant ports or break your contract. But you just have to change ISP. 3. My domain / Public or community non-profit organization. - Potentially Freedom but nomadic. Unfortunately very rare, public or community organizations offer their own domains instead. 4. Domain and servers of a public or community non-profit organization. - No Freedom, but they sometimes guarantee a minimum service and a perenniality. 5. My domain / Private for-profit organization. - Freedom but nomadic and if you get kicked out of such an organization, it is likely that you will be kicked out of another one too. 6. Domain and servers of a private for-profit organization. - No Freedom at all. They do what they want with you.
