@eddie13, you make a very good point. Initially I had mentioned in my escrow thread that all addresses I provide will be signed with my PGP key, but I didn't make it a prominent declaration. In my defense, I have always signed the escrow addresses I provided. I do you hope you are right that setting a good example will help.
Yesterday I added a very visible warning to my escrow thread, but again failed to mention the importance of a message signed with a staked key. After reading your suggestion I made the following edits to the warning:
WARNING!
Beware of Impostors!
I will only provide an escrow address here on this forum, and I will always sign it with my staked PGP key.
If your address isn't posted in this thread or sent to you through a forum Private Message, and if it isn't provided with a PGP signature assume it came from an impostor and a scammer!
