Every website that you visit collects all browser fingerprints in it's log files - it does not slow down anything.   If BPIP is keeping and processing such data, where is it and why?  No one cares if xx% of browsers are Safari, or what your preferred language is.   Remember, if you were to hide all data from a webserver, no cookies would work and most modern sites would break. 

These three services provide different types of data:

BPIP (created first) - is like the census.  It collects, aggregates and compares data, ranking and sorting.
Loyce Club (created second) - is like a library.  It contains RAW information which is harder to find but downloadable.
Ninjatastic Space (created third) - is like a registry.   You can search for specific data if you have parameters.
