Ebay Feedback

darkzrobe thought this was worth mentioning said

I am noticing a trend where Ebay buyers will use my ebay email address to sign me up for stupid shitty email lists.

How do you guys handle this?

If they do it soon after the purchase I have been leaving negative feedback. The ones that show up way later ebay says your suppose to report them to ebay but it doesnt seem like ebay wants me to contact them…
