Google caching boincstat.com detailed statistics pages

I am puzzled why BOINCStats is allowing GOOGLE to access boincstats.com users account information.

(1) If Google is accessing user detailed statistics, how much of a burden on BOINCstats servers is this?
What burden is GOOGLE on BOINC project sites?

(2) Do we users want to allow Google access to user account detailed statistics and potentially other user
information?

When I Google my BOINCStats user name Google search results list many hits similar to the following:

boincstats.com/stats/user_graph.php?pr=rosetta&id=
fr.boincstats.com/stats/boinc_user_graph.php?
boincsimap.org/boincsimap/show_user.php?userid=
www.gpugrid.net/top_hosts.php?sort_by=expavg_credit&offset


Google search results show for other countries as well:

signature.statseb.fr/index.py?offset=5200&projet=0&country
ct.boincstats.eu/.../world_cup_stats.php?
tw.dezutter.nl/stats/boinc_user_stats.php?pr
fi.dezutter.nl/.../world_cup_stats.php?pr


I could not easily find any related topics in the Forum related to GOOGLE so start one here.
