Money they raised later couldn't have been used as collateral until they actually raised it, even if the investors would still invest under those conditions.

While I understand you can't post money you don't have, that doesn't absolve them of responsibility in their user's minds (nor should it).

Hindsight is 20/20. Prior to that event happening, was there credible evidence that an S&P 500 company was going to get pumped 10x in price by a bunch of investors coordinating on social media?

I'm not sure "understanding your user base better" makes billions of dollars appear in your bank accounts instantly, but I'm not a market maker so who knows

Arguably, knowing your user base is by and large fairly unsophisticated investors who still want to be able to bet big on meme stocks suggests you should probably be building a substantial dragon horde-scale reserve for surges like this.
