The "enhanced Easy mode" of uBlock Origin consists of the "Easy mode" together with blocking all 3rd-party iframes, and blocking a list of 3rd-party resources from "ubiquitous sites".

The docs above give the example of Facebook, with these dynamic rules:

* facebook.net * block
* facebook.com * block
* fbcdn.net * block
facebook.com facebook.com * noop
facebook.com facebook.net * noop
facebook.com fbcdn.net * noop

and also mention "Twitter, Google, Disqus, etc.".

I have two questions about this; can anyone here kindly help me?:

1. Is there a list of URLs for other "ubiquitous sites"? Any that you suggest?

2. Are any of these already blocked by the static rules? For example, I'd think of blocking google-analytics with

* google-analytics.com * block

but I wonder if this is redundant; I suspect such block already takes place in one of the default blocklists. Or?
