One fun option could be to spam the spammer with off-topic conversation, thus wasting their time. https://ted.com/talks/… Perhaps not TOO off topic, maybe a dozen or so emails about growing garlic for market ought to get you off the list for good. Or, maybe, a few essays on how to grow fingerling potatoes (subsequent emails can include recipes for both your garlic and potato crops, I like mine scrambled with eggs and wrapped in a tortilla). You get the idea... Travis Owen Rogue River, OR http://www.amateuranthecologist.com/ http://www.pacificbulbsociety.org/
