Another wall hanger licensed today...let's see what Alamy CR will say...
Just received the following reply from Alamy:
"We have no reason to believe this is being used outside of the terms of the licence. If however you do have proof that it has been, let us know and we can then investigate."
Standard answer, as you know.

Still, they could hardly go after a buyer without proof of use outwith the licence purchased.
I wonder what use is being made of it, given that PU sales tend to be better earners, at least for me, than many 'regular' sales.
This morning I wrote them my third email about an unreported sale from September.
First contact form sent when I found it on 11th June.
Answer: "We'll ask the customer's account handler to look into this and we'll get back to you."
Second email sent 19th July: "Any word on this yet? I wouldn't have thought it would be difficult to chase up given thatthey have an "account handler".
Alamy's answer: "We've just chased our colleague about this - apologies for the delay. We'll get back to you once we have an update."
This morning's email from me: "Another month has passed, and this image has STILL not been notified or paid for. You need to move much faster. What is your extra 20% doing for us?"
Waiting for the reply.
PS: note that a sale I should have got 50% on will now net me 40% (what they've said to others who have asked).
