We are looking at ways to limit this in a way that doesn't hurt benevolent users (e.g. ones coming from behind the same CGN) and that is not a whack-a-mole exercise. > Now while I myself don't particularly care about credit farming on > RIPE Atlas (After all RIPE Atlas credit is kind of like Monopoly > money), I do care about things becoming biased towards these software > probes. > > For example, when I had selected for a selection of probes in Brazil I > ended up with several of these software probes giving me the exact > same results. this is not very useful and this has the potential to > bias academic measurements, had I not looked at the probe list > results this would not have been immediately obvious. One crude short-term solution to this is to exclude software probes (system-sw). A longer term -- nicer -- one is the "probe similarity" idea, where you can (will be able to) ask for dissimilar probes. Unfortunately that's not something we have yet... > Is there an immediate way to report these probes other than this > mailing list? I don't know of one and so I'm here :) You can always send mail to atlas at ripe.net - which is the general support address for RIPE Atlas. Regards, Robert > Cheers > Ben >
