Here's the background:
I run a photolab doing fine art quality inkjet printing for photographers and artists. My website has a link to an FTP upload page clients can send picture to for printing. After uploading, they are instructed to call or email me with instructions and contact info.
It's a useful feature for my customers, but the majority of pictures uploaded are basically spam, mostly mobile phone snapshots (but not always) and many of these seem to be from Asia, with a preponderance of stuff that appears to be from Indonesia, based on signs and text seen in the pictures. A lot of it features goofy teenagers mugging for the camera.
No orders are ever placed for prints, no further contact ever occurs.
Most of the pictures are small, although every once in a while I'll get a 5-10 MB file. Sometimes the images appear more "serious" but they still turn out to be spam. And it's not a drag-and-drop uploader; you have to navigate to the file on your hard drive and then click the "upload" button.
So, gaaahhh-what is going on here? I've had hundreds, if not thousands, of these over the last decade. I can't believe teenagers around the world have come to my website in a giggling conspiracy to drive me nuts, but that's what it seems to be!
If this is some weird robo-spam operation, what is the benefit to the perpetrators?
Anyone have any ideas what's going on here?
