[atlas] Possible software probe "farming" on AS47583

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

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.

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
