This was the first time I heared about your issue, so I checked what they had to say on the matter.

Complaints about email spam with a MEGA email address: https://help.mega.io/security/data-protection/complaints-abo...

TLDR hypothesis - You get daily spam from a third party, using spoofed email headers, but I'm sure you'd figured that out already

Sorry, that is correct. I can't delete my comment. The mega.nz appears only in the from field. I see they use SPF.

You can possibly try to contact dang via [e-mail] to request that comment to be deleted. As a general rule, replied to comments can't be deleted by a user.
