I would contact theymos about it. If someone is spamming their email address then he will possibly remove the email address from your trust.
My understanding is that the only exception to the policy of no trust moderation is in cases of obvious spam
I'm not sure if this is true, I believe the trust system is mostly left unmoderated except in extreme cases. For example
dogie's untrusted feedback is almost entirely pointless spam, yet nothing has been done to remove it, although that might just be because dogie never requested for it to be removed.
i know that Mitchell (bitcoininformation) has said that theymos removed feedback from someone spamming his feedback.
The difference is that doggie has a bunch of baseless claims against him while the OP has an email address that is not claimed to be owned by the OP by the person leaving it. The intent of the feedback left is to get people to contact the person leaving the feedback via email
I don't think it would hurt to ask.
