As with any other site, if you accidentally reveal your email address, there will be the "one" who takes advantage and sells it to the spammers and phishers.
That's where I checked my email accounts. Pretty good but, they sometimes miss a few.
Not only that, we need to bounce all spam email addresses and servers. If using Outlook (Office 365), one could have a rule that if one receives an email from a certain address, it could be deleted permanently, but that takes up much time eliminating each spam email. I also use yahoo and gmail and only occasionally get spam, but the spam in my hotmail has increased lately
You don't even need to reveal your emailadress on some site or forum. Because as the default setting in any email client (the online 'clients' as well) is that any adress you send a email to will be added in the adressbook. When someone's mail has been hacked after that, the hacker has all the adresses in the adressbook to be used and to be sold.
That depends how they use it, I use Proton for general contact, it is even listed on github and zero spam.
I already known mine has, from data breaches - checked it before. I still stuck with it. But interested to see there was a recent one:
Twitter (200M): In early 2023, over 200M records scraped from Twitter appeared on a popular hacking forum. The data was obtained sometime in 2021 by abusing an API that enabled email addresses to be resolved to Twitter profiles. The subsequent results were then composed into a corpus of data containing email addresses alongside public Twitter profile information including names, usernames and follower counts.
Compromised data: Email addresses, Names, Social media profiles, Usernames
As expected, they are not responsible for Outlook emails so that was a waste of time asking
