Hey I have a problem with downloading logos from the site while captcha is enabled on the site I mean downloading a picture for example on discord apllication using links such as https://ikabyte.com/logo.png does not display on discord

That's because, when Discord (or other platforms) embed the image like this, they send a request from their server to try to get the image. If that request is challenged by a captcha, they can't embed the image. In whatever rule you have created to always show the captcha, you should add an exception for "Good bots". This will let sites like Discord go through.

#

the embedding proxy isnt following robots.txt

#

so it doesnt qualify

#

also they use generic AWS, GCP etc

#

this is my check for discord:

(
  (ip.geoip.asnum in {14618 15169 396982})
  and (http.user_agent in {"Mozilla/5.0 (compatible; Discordbot/2.0; +https://discordapp.com)" "Mozilla/5.0 (Macintosh; Intel Mac OS X 11.6; rv:92.0) Gecko/20100101 Firefox/92.0"})
)

#

first UA is the embed proxy

#

2nd is the image proxy
