1) if the BOINC project servers were down then gridcoin would continue to function as a normal PoS coin and when they are online again you get the PoR bonus again
2) I think the BOINC foundation is very trustworthy and the advantages of contrubuting to science outweigh the disadvantages. Also BOINC itself is totally independent from gridcoin and well financed on its own for the public good of citizens contributing their computing power to science, so if they would tinker with the stats they lose their credibility and this would have consequences for them, eg. loss of fundingg or another team being funded to run the project servers, the software is open source anyway.
