is there a way to reliably identify a facebook bot by IP?
My site is getting hammered by bots claiming to be facebook, but how do I know for sure? I'm looking for some kind of official procedure to validate a facebook bot similar to what Google recommends for their bots here.
Can I perhaps parse OrgName in whois and trust that? Or can that be fake?
I'm answering this for the sake of keyword indexing in the internets.
Indeed, it looks like the best way to identify a Facebook bot (Facebook Scraper) is by matching IP to the range of declared official Facebook IP ranges that can be acquired by running
whois -h whois.radb.net '!gAS32934'
