High Cpu Usage - Spammed by meta?

I seem to be getting spammed by these

I have no idea why, in 1 week this particular user has consumed 5TB of data. And by analysis it seems to be spamming from facebook. Any idea what i should do?

I have tried disabling the meta pixel does not seem to change anything.

If that’s the real facebook crawler, you could add this to your robots.txt (it should respect it):

[other rules]

User-agent: meta-externalagent  
Disallow: /cart/  
Disallow: /checkout/  
Disallow: /*add-to-cart=*  
Disallow: /*remove_item=*  
Disallow: /wp-admin

5TB are a lot for a stupid crawler, I would have blocked the IP range 57.141.16.0/24 days ago.

I ended up blocking the IP range and updating the robots.txt, and that seemed to have stopped it for now.. I saw on reddit that recently theres an uptick of meta crawler for AI. But this is the most aggressive i have seen in sometime, maybe it was broken.

Check my posts here. I had my servers freezing due to several AI crawlers, and them not respecting the robots file. I ended up blocking 10K+ bot IP’s and ranges.
