Here's an update.
I opened a ticket with Yahoo webmaster support. I had 2 escalation notices and then a customer support survey request.
A bit disappointed with this. At first it seems Y support were onto something but now silence.
Definitely something not right here. I still get the sports book 404s (which could be Ys mechanism for testing 404 responses - it says that on the webmaster support page).
The exploit trawling looks more worrying though. Could it be that someone has found a way to use serps as a sort of proxy to find sites with potential exploits?
