Rich people will say, money doesn't matter. But they haven't experienced actually not having it. It's ironic.
Attractive people say, looks don't matter, but they've always had good looks. It's ironic.
The joke plays on the way deleted comments on Reddit show up as removed by deleted user, sounding similar to the earlier ironies: Deleted says deleted. Since that last is effectively meaningless, and entirely different underneath from the reaction-to-judgement underlying the first two, it's also humour from the non-sequitur.
So it turns a frustration with rich and attractive people telling us not to worry about money and looks, into a surreal joke comparing the pattern to deleted Reddit comments.
I took it to mean that if you weren't rich or beautiful, you would be censored. The censorship being a way to show that you weren't important.
Of course, that wouldn't actually be the case in real life, though it may feel that way. If we were looking through the lens from a big data company, it would be true that we're just one data point in a sea of data points, but they rely on the sea and the sea is made of me's.
