Yeah, the + trick is not that great, because it is quite obvious what your real email is. This way, not so much. One could of course still guess that you are using this trick when they see that your email matches their domain name. If you're paranoid about that, you could of course just use <random string>@yourdomain for every login. And store that in your password manager.
- y03a 9y agoAnything at a custom domain that doesn't look direct to an individual (e.g. not realname@domain.tld) is a big hint to spammers that the owner uses a catch-all and thus any address will get the job done. I suppose you could go with a whitelist for every random address you give out and blacklist the ones that misbehave, but that's a lot of work and, since every company misbhaves these days, including entities like banks, you'll likely miss emails you actually need.
- ibz 9y agoI don't care much about spammers. The filter at FastMail is good enough. What I care about mostly is to make automatically correlating my identity between different websites harder.
