The biggest problem with small projects is the small amount of hardware behind them. I was reading posts on the official message boards and it seems as though the admin of this project is treating it like a hobby and only had access to the server on Wednesdays. Even then the server seemed small and was only capable of 30GB of WU's.
Before white listing a project the admins of the project should be consulted with and an action plan come up with in order to handle the additional influx of users.

My recommendation would be for the users who received a large amount of Gridcoin from this project for little work done is to donate it to the project admin of Sourcefinder so that they may be able to put the money to good use in upgrading the back end hardware of the project. Of course it probably wont happen.
