The main problem I have with those services is that there are so many of them.
It may well be that there is some purpose in having research data available for some
purposes, but at this time the amount of traffic for all that scanning from all those
different companies and individuals that do it causes more traffic then the actual useful
traffic by the users.
When we would route that all into our radio network, it would overwhelm the network.
If it would be only a single service that would be scanning at a responsible rate, I would
have less of a problem with it.

As someone who uses censys scans a lot when doing research, I'd be very sad to see
more networks blocking censys (or wasting effort blocking port scans in general). I'm
in network security and I don't bother to block these, even. Unless it's actually
interfering in some way with your operations, it is completely harmless and allows us to
answer questions about what kinds of things people are doing with the Internet.
