One thing is flagging (just like this), another thing is showing a different version of the site based on the user, the latter is scammy and is meant to give users the felling that their post is there (while it's not) but no one is looking at it.
Showing a different website to users is something really nasty.
A link aggregator that can decide which links to show.
It wasn't anything controversial just a video showing unsolicited connections made by firefox, to support my theory that browsers developers contribute to mass surveillance.
Facebook has no authority in this, except to remove them from their contents.
Facebook has instead a board of greedy people who want to maximize their income, regardless.
It probably is a way of circumventing some browser settings that like:
```
Isolate requests to First Party domains
```
It doesn't sound right, and honestly i don't need to tell you that they can change the contents there whenever they want, or start a mail server sending emails on behalf of your subdomain(?)
I mean i can see countless reasons not to.
Not to mention competitors who want to de-rank your domain.
The human nature is bad, "homo hominis lupus" said a guy....
I never got blacklisted using the same domain and server for more that 4 years now.
What was your provider? Sometimes you get an ip address that is blacklisted already...
I use Hetzner or Privex
