Gold mailed to me from stranger - what would you do?

OP here… I have put the person on my friend’s list but he hasn’t come on.

I feel that he has kept my mailbox hostage as I do “open all” on occasion, like I did this morning and the gold just poured in.

I am puzzled at Blizzard’s response to return or delete it. Why would I delete it? That doesn’t benefit me or the sender.

I am curious to see who the sender was, at any rate, to see if he’s a normal player… which may influence what I do with it. Perhaps he is just appreciative that my AH toon provides good value to the community and thus the “ty” in the subject line. Perhaps that is the interpretation I should go with.
