Detailed build reports with logs are not anonymous, clients will need an
account on hackage (ie username and password). Yes, we could get flooded
with anonymous build reports, but they're much smaller and hopefully
they'll either be obviously bogus or drowned out by the volume of legit
reports. So the information content and reliability of each data item is
lower but hopefully the volume makes up for it, so long as we do the
statistics carefully.

As Manlio says, we're always open to DOS attacks. We just have to make
sure we're not more vulnerable than average by doing too much work on
the server side compared to the work done by the client (ie the
processing of anonymous reports has to be fairly cheap).
