I feel the need to say that I'm not in favor of constantly second-guessing every boinc project. IMHO if it's BOINC it's good as long as it fits in the whitelist criteria under vote right now (https://github.com/gridcoin-community/Gridcoin-Tasks/issues/194).

Let the users determine usefulness. As long as a BOINC project exists and as long as they are fair on their point distribution (not gaming the system), let it be.
