> What is the issue around moderators of a service you signed up for, contacting you via the email you provided to use this service?
My email address is personal data and as such it's legally required to be
collected for specified, explicit and legitimate purposes and not further
processed in a manner that is incompatible with those purposes
Using it to contact me about my comments as a moderator is not compatible with using it to reset my password, which is the only specified, explicit purpose that I (could have had) supplied it for.
