A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

You can append to your existing e-mail address in various ways, and this could be pretty useful for seeing who leaked your e-mail address to spammers. For example, for your bank, give them the address myaddress+banking@gamil.com. Then, if spammers send to that address, you can quickly see where they got the e-mail address from!

I've tested it with Proton Mail, and it works in exactly the same way.

I used to work for a product comparison company (think finance and insurance). We used to save the email address as typed for login and also with everything after the plus removed separately. For Gmail and certain other large providers, we also stripped out any dots e.g. a.j.uniquename@gmail.com became ajuniquename@gmail.com.

Now you can tell us who you worked for, so we can be sure to avoid them...

I'd rather not dox myself. They're not a huge company. I promise you that this is not something uncommon.

Sorry, I thought the rest was implied. Because the company also sold user data (and stated that in the T&C's). The industry is very aware of email aliases and so it is more valuable to have sanitized data.
