Sad facts. If they can't provide enough work for "everybody", then they shouldn't be on the whitelist unfortunately. :(

And I can vouch for the fact that the way they release workunits is in no way malicious. Gridcoin has a fairly good rapport with the administrator of the project, Sam Foster, and he has been forthright in all communications. It is even his own suggestion to remove Sourcefinder if it's causing us troubles.
