Accounts are free to make, so bad actors will just create and "season/age" accounts until they have the ability to flag, then rinse and repeat.
I think the biggest thing HN could do to stop this problem is to not make flagging affect an article's ranking until after a human mod reviews the flags and determines them to be appropriate. Right now, all bad actors apparently have to do is be quick on the draw, and get their flagging ring in action ASAP. I'm sure any company's PR team (or motivated Elon worshiper) can buy "100 HN flags on an article" on the dark web right now if they wanted to.
Why would a company like any one of Musk's need to buy these flags? Why wouldn't they just push a button and have their own bots get to work? Plausible deniability?
Who knows whether or not both happen? Ultimately, only the HN admins, and they don't disclose data, so we can only speculate and look for publicly visible patterns.
You can judge their trustworthiness by evaluating their employer's president/CEO, who dictates behavioral requirements regardless of the personal character of each employee
