Facebook Bots

[DigNap15]

Hello I have a xenforo forum, and am very pleased with it.
Sometimes I have quite a few Guests, many of which are Bots.
Some are Google and some are Facebook
I am not sure that I like Facebook crawling through my members content.
Is there a way of stopping this?

Thanks for that, that was very interesting.
I now realise that it means that some of my members are sharing pages with their friends, which can only be good, as I might get some new members from it.
So in some ways its good to see the Facebook bots

The other day I had a major problem with my web host who told me I was using far too many CPU executions, so I had to ugrade to a cloud server
I only have 1000 memebrs, of whom about 400 are active, but they are very active flipping from page to page and posting and reacting. I imagine that is what you mean by thousands of calls

I have noted your code and suggestions
