ps1: I don't know any of these people (owners of the accounts) but their exposure is pretty high which means a that their posts have high impact on other accounts.
ps2: List is way bigger.
ps3: Nubank is just one example. Things can be done with any public account.
ps4: Please, do not waste your time and money using paid software. It's time to move forward. R is free. If you still want to spend money I recommend hiring someone to teach your team (it would be way less expensive anyway).
