Hi everybody, While doing some measurement work earlier this weekend I discovered that there are a large amount of probes on AS47583 that look like they are being set up to farm credits. With a suspiciously high amount of purely software probes on the same IP prefix and sequential IPv6 addresses. $ curl -s 'https://stat-ui.stat.ripe.net/data/atlas-probes/data.json?resource=47583' | jq .data.probes[] -c | grep Connected | jq '.address_v4 + " " + .address_v6' | sort "153.92.14.66 2a02:4780:6:c0de::e" "153.92.14.67 2a02:4780:6:c0de::f" "153.92.14.68 2a02:4780:6:c0de::11" "153.92.14.69

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. 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 :) Cheers Ben
