Honestly, how is this allowed?

Well they are free companies. Maybe they are just real estate free companies. They should get themselves onto the big property websites with all those properties.

But jokes aside, it's odd that a single FC can have more than one.

The thing is, a single FC can't have more than one house. However, on a technical side of things this is not the same FC. FC tags are not unique, multiple FCs can have the same tag (e.g SHELL as seen here). So what you're seeing is multiple accounts having multiple FCs with the same tag. And because this is done with multiple service accounts, it is technically also not breaking the ToS. So they are following the law by letter but ofc not in spirit and this is the result.

Edit: Also, what LianaThorne says, although this is not a Dynamis issue at all. This crap happens in every Datacenter plenty of times. I suppose in Dynamis it's just easier to establish because there's less competition when a DC is new.
