I don't have a Twitter account so I cannot directly speak to that. However, I did have a FascistBook account and I cannot begin to tell you the experiences I've had with them.
I can also tell that Mark Levin decided to reopen an account on Twitter after leaving for the treatment he used to get. Don't forget Twitter kicked the president of the United States of America off of their platform because he didn't toe the leftist line.
I do now that at least on FascistBook they do allow some conservative speech if it's not "controversial". If it is a little controversial then the Fact Checks start getting attached. Then the next step is to cover the comment with a warning message that you have to click on to see what was posted. After that comes the warnings. After the warnings comes the time outs. And each timeout gets longer. It's not like ImgFlip where the most you get (at least the most I've gotten) was 24 hours. FB will kick you off for a month. The most I got was a week but my friend got put in timeout for a month.
So the fact that you might see a mild conservative tweet on Twitter does not mean that that you are seeing them all. I am guessing that Twitter, prior to Musk, had the same communist... Opps I meant say community standards that FB has.
There's a lot more that happened to me and people I know on FascistBook than what I have told you.
