Recently I have problem with Open Graph checkers unable to detect Open Graph data?. It turns out that the bots from the checkers are unable to access data. However, since I have no root access to my shared hosting, I can't use wireshark to know the exact bots that connects to my hosting, therefore cannot ask the technician to help me.
So is there a way to know the bots? I really have no idea where to start. The site I want to know is https://developers.facebook.com/tools/debug/og/object/
