And that's before considering the insane uphill battle any social media platform has to fight to become as popular as the likes of Twitter, Facebook, etc - assuming the presence of "disgusting content" does not limit its ability to ever scale that much to begin with.

Btw, I'm using the phrase "disgusting content" to quote the OP because I can't think of a more appropriate phrase, not to indicate sarcasm or cast doubt on the nature of the content. I've never been to Parler, but I trust that there was some pretty awful things being said there.
