Websites blocking e-mail aliases
(beehaw.org)
Privacy has become a very important issue in modern society, with companies and governments constantly abusing their power, more and more people are waking up to the importance of digital privacy.
In this community everyone is welcome to post links and discuss topics related to privacy.

A tip is to host your own domain at an e-mail provider that allow you to receive e-mail for any recipient in a single mailbox (i.e. catch-all or wildcard), and use the following alias format when signing up at different websites or services:
<website>@<yourdomain.tld>
This allows you to filter incoming e-mail by which website/service you signed up for, regardless of what domain they send e-mail from (it can be different for account notifications vs newsletters etc.).
It will also help you detect if they have sold your contact details or had a data breach without announcing it publicly, since you wouldn't use that specific e-mail alias elsewhere.
