How did you create 2 fb accounts? Don't they ask for phone number confirmation?

I don't think so. I have 3 accounts (I never use any of them, or FB at all, these days, but they are all still active). None of them are in my real name, but all have plausible-sounding names.

I have several private FB accounts. I created them when text message verification wasn't required. But if I had to do it now, I'd have bought a couple of cheap SIM cards and still set it up the same way. I feel it's important to split your account into several ones instead of using groups of friends as recommended by FB. It's harder to profile and track you, you have more freedom and privacy in expressing yourself, you mitigate several risks etc. Only one of these accounts has my real name - I log in every couple of weeks and just accept invitations (if I care to). The other ones use common names to protect my privacy. For example, I have a separate account for reviews. Reviews are important tool for consumers to influence the quality of service/product. While I don't want to hide behind a fake name when writing a review, and if asked I can reveal my identity to the organisation in charge of the product/service, I definitely don't want everyone to see what products/services I'm using. That's just one example - if you have to use social media, do it in such a way you have at least some control in this unequal battle.
