Buyer calling eBay to remove feedback

[vwrestmania]

A buyer offered to call ebay to remove a neutral thereby also removing the low DSR. I can't send a revision request since it's been more than 30 days.
Does the buyer calling ebay bring any unneeded attention to my account which could cause harm?

If i'm correct neutral feedback can be revised only negative... at least that's what an eb rep told me awhile back

even a postive can be removed, but it has to be via CS
