This just happened to me. I didn't know about the no comment, only PM thing. Some random guy messaged me and asked me to email someone else saying that was the contact info for the lister. I didn't fall for it, but it was definitely something I did not expect.
I have a DPP from several years ago. It's nice and crisp, but now that optics like the Gideon SRO knockoff are available, I don't really find the DPP as appealing.
