A reasonable question. In this case by "serious" I mean a proposal with a significant body of support behind it. If the bar is "own $2K of stock for a year" to get a proposal made then it is very easy for, as I said, "some person" to get a proposal on there that has no meaningful support and no meaningful chance of passing. It doesn't mean it was done by someone who holds exactly $2K of stock for one year of course, but at the scale of twitter even $500million of stock would put them very distinctly in the minority.

"Meaningful support" and "meaningful chance of passing", of course, has nothing to do with morality, goodness, or any other such thing. I'm in a fact mode here, not a normative mode; that comes after facts.
