I actually remember this being a thing back in 2015-16 when they first launched and before the "boom" happened. Back then it was only possible when you actually got an invite from somebody to join a server though, if I remember correctly.

But back then there was no official way to browse more or less public servers, which is the case now. I guess to join those it might be good enough in their eyes to just create a temporary account to let users test the waters and hopefully later convert into a proper account.
