I'm not sure if we already have this, but I was thinking about it after hearing another sad story of a scam today. A fair number of scammers use similar listings, phone numbers, email addresses, etc. (example that I am familiar with, the hyacinth macaws). Perhaps the Avenue would benefit from having a gathering of these known scams to better educate members/guests, with maybe some tips on how to adopt from unknown sources.
Just a thought, it just makes me so sad to see these stories
