There's a bunch of influencers who go help struggling people. I'm certain the majority of them aren't doing it out of principle, but at the end of the day people still get helped.

I don't know for sure, but I suspect it's like a lot of other things on the internet, with a bimodal distribution between people who get helped a lot ('Sir Hype surprises homeless former billionaire with a MILLION DOLLARS!') with many other similarly deserving people getting nothing. I prefer systems with a lot of people who get helped sufficiently to avoid hitting rock bottom in the first place.

Besides the fact that these undertakings are about promoting the benefactor (and the near certainty that some of these professional philanthropists will later turn out to devils LARPing as angels), it also makes the determination of moral worthiness turn on the public's fickle opinion about whether the recipient is sufficiently beautiful/ ugly/ unlucky/ desperate/ degraded enough to qualify. Charitable undertakings involving cameras are always a bit suspect.
