Are there any counter exploits against scanners? e.g. jam the scanners for a very long time, an infinite loop, or memory leak them.

  Depending on how badly their scanners were written you could jam up their efforts by tarpitting them (at the expense of some resources on your side). Alternatively you could try ZIP/XML bombs to crash their process or mismatched Content-Length headers to maybe cause buffer overflows. Elsewhere in these comments someone linked a Python example on Github for how to accomplish this. The general trick seems to be: look at the rules of HTTP(S) and break them in fun and creative ways. Lie, break the standards, do weird networking stuff. If they're coming from a country with an oppressive government that you don't mind risking a ban from, you may be able to get their government's firewall to get rid of them by sending forbidden texts, or HTTP 302 redirecting them to search engines with forbidden texts in their queries. For residential Chinese scanners, for example, querying for information about the Tiananmen Square massacre can cause the entire internet connection to get dropped for a short while. This may not work well with data center/server connections, but it can't hurt to try.
