How to completely block the Pinterest Crawler?

Hi there!

We’ve been getting spikes of human-like traffic from the Pinterest crawler that has messed up our Facebook pixel and data. It’s the only bot I have seen that behaves like this, and Pinterest support can’t help. (they told me it’s related to rich pins needing to update every day, but I don’t know how to, or even if I should disable it)

From their site:
“Pinterest’s IP is dynamic and thus constantly changing, but will always be in the range of: 54.236.1.XXX.”

I couldn’t figure out how to block the whole range in my firewall, and added Pinterest’s IP is dynamic and thus constantly changing, but will always be in the range of: 54.236.1.1-100 manually, and it seemed to work. But it’s back again now, and I don’t have any means of finding the ip the bot used, so I guess I’ll just need to get the rest of the range blocked.

I also tried blocking the user agent, but without success. And I don’t know if it’s working or not since I can’t find any stats for that.

Here’s the page from Pinterest about the bot:

Any help with this is more than welcome, as I really don’t want to manually add 800 more ip’s :sweat_smile:

Thanks!

You can try adding a IP Access Rule (Firewall > Options) for the block 54.236.1.0/24 with action Challenge or Block
