Nemo recommended insource: to Lagotto because it would actually work and do what they want, but didn't consider the computational cost on our end. However, if we only allow 20 at a time, they would probably monopolize it entirely. In my sample we got about 50,000 of these queries in about an hour.
David/Chad, can you look at Nemo's issue and comment there on what's plausible and what's not?
Also, is this the kind of use case that we want to support? I'm not suggesting that it isn't, I really don't know. But they aren't looking for information, they are looking for something akin to impact factor on reputable parts of the web. If that's not something we want to support, how do we let them know? If that doesn't help—e.g., because it's some other installation using their tool that's generating all the queries—do we block it?
At the very least, we should ignore these malformed queries in our own metrics.
