I'm getting an email 1/week asking me to "Confirm Roll20 Email Subscription Status" from "<a href="mailto:no-reply@roll20.net" rel="nofollow">no-reply@roll20.net</a>" the link in the mail goes to <a href="https://con.roll20.net/hs/preferences-center/en/page" rel="nofollow">https://con.roll20.net/hs/preferences-center/en/page</a>? Is this legit or spam? I had a look in my account settings and the only email options I can see are daily digest, instant msg, none as contact options for forum boards.
