Today I received spam to my e-mail address I’m using on MetaBrainz.
The e-mail address I’m using on MetaBrainz is from ProtonMail (only by web mail, strong password) and I’m just using it on MetaBrainz, but I’ve used it also on Facebook (end 2017, account closed mid 2018, rarely used, no apps).
I never published my e-mail address.
I never get spam (to this address) till now.
So I see just two possible leaks (beside my computer and the mailbox provider): MB and FB.
Are there known leaks on MB? Does someone have problems with spam, related to MB?
