The answers from DPC:

"They are not cheating" (which is indeed possible)

"We have no right to accuse them" ( not even if we point out what we are suspicious about... freedom of speech seems to be irrelevant)

"Until we can actually prove they are cheating they refuse to use another method to buffer there candidats... it works for them, so why change it" (even if they would get the same results with the non-cheating method)

"They are reluctant to answer any questions about their computers or output" (because people could lose jobs over it and it's none of our bussiness how and where they get the results)

"We should talk to the project leaders (Charles) if we think there's something wrong and they (Charles) have to prove what's wrong by showing serverstats, uploadstats or whatever... IF there's something wrong with the results they (Charles) should prevent people from using the 'result.dat-copy-method' by changing the program, method to up cands or whatever." (until then, they will NOT stop using this method which is know to be 'the' method where cheating is possible, even if you can buffer in a non-cheating way)

This is a personal translation of the opinion I can detect in the answers I get... (just stating the "personal" part before CowArt says I'm not translating exact sentences )
