Twitter have stopped doing blue ticks except for political candidates. They rely on outside entities to do it for them which I thought was strange...

Some teen was able to fool them with a fake profile:

(Yes I know its CNN but they give some insights into what the process is these days).

For famous people like Trump, Prime Ministers, Presidents etc yes.
For ordinary people like you and me, you don't need id to join Facebook or Twitter or Parler or YouTube or social media.
