Any idea on this one?

Just spotted a bot that we've not come across before.

The full User Agent string is:
hoge (co2h2onacl@gmail.com)

[Mods, this is the actual string as found in our logs - if inappropriate in any way, kindly do the needful, as required]

Does anyone know what's this?

We'll also dig more and post findings here.

A few basic Qs, please...

- From whence did it come? (This forum's Charter link, above, shows how to best indicate individual bot-running Hosts or IPs.)

- Did it read robots.txt?

- Did it heed robots.txt?

This bot's new to me but Bots vs Browsers saw it in June: [botsvsbrowsers.com...]

FWIW: The "co2 h2o nacl" bot-maker must be into chemistry, too: CO2 = Carbon Dioxide; H2O = Water; NaCl = Sodium Chloride (salt).

My bad, Pfui :-)

Came from (Hong Kong - APNIC)

robots.txt - no read, so no heed ;-)

Yes, the 'chemistry' is quite interesting.

Will keep a watch and post further findings.
