Question, I must have been tagged on the many data breaches. I keep getting emails stating I have approved

3. email addresses have been hacked or sold for ages.

If you are an Apple user, the iCloud "plus" lets you set up temporary email addresses that you can withdraw later (or not) for signing up for stuff.
Perhaps other email providers have this as well/

But once it's out there, it's a matter of filtering as your provider can, and your email program can.

Just don't reply or "unsubscribe" to any really crappy looking email. That just validates your email address in case they sprayed random ones looking for a hit. That's how they guess a lot of passwords. People use common ones.

Sites like Yahoo, LinkedIn, DocuSign and others have been hacked and email addresses stolen. In some cases, the password protection was so weak that even those were grabbed. I changed all the old passwords I ever used, and will never use them again.
