I think they mean in terms of workload, not like pay or something. Either you have a lot of work, or very little work. But when you’re needed, you’re needed urgently.

I think it was specifically for mobile - I whitelisted the facebook domain (easy) but blocking various ad servers would also break functionality on the site.

I might have to try that. I had pi hole set up but my gf couldn’t use facebook so I was politely asked to remove it
