As I understand it, you are claiming that BobRTC is protected from things that are relevant (like fake or malicious accounts) in a way that FireRTC is not.
First of all, a bad actor using a bot, or creating lots of accounts, is simply NOT a relevant issue (as far as I know, those are simply not problems that FireRTC has had to deal with). So is BobRTC, with its requirement for a Discord account, protected from a bad actor who wants to use a bot or who wants to create lots of accounts? Maybe. But who cares, because that is solving an irrelevant issue that is not a problem.
FireRTC doesn’t require credit card information to make calls, and as far as I can tell BobRTC doesn’t require credit card information to make calls, so I don’t know why you are talking about credit card information.
Let me recap for you the problem that FireRTC faced (as I understand it), and explain to you why (as far as I can tell) BobRTC has not solved that problem.
As I understand it, the problem that FireRTC faced is that a bad actor used FireRTC to make an ILLEGAL call to a legitimate party (not a scammer) who didn’t like it, and they took legal action against FireRTC.
I could get a throwaway e-mail address and a throwaway telephone number, and I could make a Discord account using them. Then I could post a number for my high school to https://bobrtc.live/. Then I could use BobRTC to call my high school and tell them that a bomb will go off in the school in 2 hours. Do you see the legal problem that BobRTC did not solve?
