Ad hominem fallacy, used to discredit a claim with unsupported and irrelevant accusations.
"come up with ur own content that is worth upvoting"

"turning this platform into some nazi censorship"
Godwin's Law. A lazy way to try making the other side seem bad by calling it something it's not but everyone hates.

Even free markets have rules. If I hack your account and take away all your earnings, will you say it's free market, so it's ok?
Even more sad is when the person is hiding behind an alt-account.
