Might want to obfuscate that address a little – perhaps replace the @foo.bar with "on ProtonMail's dotcom domain" or something, if it's worth it to stay off unsophisticated scraper lists.
Maybe I'm too cynical, but I pretty much assume that any email address is "compromised" (as in no longer spam free not pwnd) as soon as it is created. It may not be that bad, but I honestly believe the first time the email address is used as an ID then it is.
It's not binary, as in, either "compromised" or not. There are lots of different spammers using different methods. Posting your email address on a public website will dramatically increase the amount of spam you get.
If you put an address on an "About Us" page or something you might get some business related spam now that WHOIS data mining is dead, but regular 'ol users you want to target haven't posted their email addresses in HTML for 10+ years now.
