While the social part is not there, the technology is.

I subscribe to rule groups through hostblocker.app, which pulls HOSTS files from different known websites and compile them into a .lsrules file which Little Snitch can use.

While I cannot vouch for the website's underlying code-I did not write it and I can not find an open source implementation-It only provides rules and I can edit any rule group to my liking after subscribing to it.
