@stux@mstdn.social block their entire ASN? it will make at least them spend money by using another network

@athos@bolha.one @stux@mstdn.social They have a whole page about their crawlers and a handy command to get all their IP address blocks from their ASN: https://developers.facebook.com/docs/sharing/webmasters/web-crawlers
I suggest checking that every so often and updating the address blocks accordingly
