problem with facebook

hello, I have a problem with Facebook. The problem is when I create a new account which is a fake one just to post on groups after two hours or max 24 hours they ban the account and sometimes they ask me to add a phone number and when I add it and receive the confirmation message it doesn't work. help please how to overcome this step and create an account without being banned.
Also is there any possibility to create more than one account and open it from the same laptop.

Thank you

Yep you can open the account but each time you need new number to open the account.
So, you have some specific numbers i think
