To understand the meaning of 35.black we first need to understand the working of Facebook, Instagram or other social sites.
Basically whenever we Post something on such social sites, or Send a text or comment in the following format

"log.in"
"sit.com"

basically, when we type any word that is also a TLD that means a Top Level Domain followed by a 'dot' "."  on Facebook or Instagram, the servers automatically detect it as a webpage URL.
you can try and check it yourself

For example, if you are chatting with someone and while chatting lets say you sent the word "login" to your friend over chat, then the word will be sent as you typed.
But in the same sentence if you intentionally or accidentally add a 'dot' i.e. "." then the Servers will take it as a URL and send the recipient an link instead of the word you typed.

Here when you add a 'dot' in "login" and write it as "log.in" then the word will transform into a URL.
This happens because as we all know that ".in" or "dot in" is a top level domain.

Similarly ".black" or "dot black" is also an top level domain and when we try to type 35.black without space on Facebook or Instagram, the servers automatically detect it as a URL.
