I show the IP as blocked:
OrgName: PacketExchange, Inc
NetRange: 70.39.128.0 - 70.39.255.255
CIDR: 70.39.128.0/17
and also block .in as referer. Untrusted might be added as a UA if I were to see it doing naughty things.

As to why the search query, my guess would be that he secretly admires the technique you are using and would like to emulate it or is using it as an example somewhere to tutor others(?) Since the result is not visually showing anything 'useful' maybe the idea is to visit the source.(?)
