Seems like in real world use it makes a difference.

From another thing I read, people have a tendency to not apply enough sunscreen or apply it correctly. I’m sure if everyone did it perfectly it wouldn’t matter. All I know is anecdotally, when I switched to 100 I stopped getting sunburns, and I have been in situations with people who used their own lower spf, got a little burned still, and I came out of it pale white.
The price might be higher, but a quick look on Amazon and I’m seeing more than spf affecting that. The brand I buy is about 1.80 (usd) per ounce, and i see other brands with less spf for more. I see other brands with the same spf for less, and it seems like it’s between ~1.10 per ounce to ~2.80 per ounce so I’m not really bothered by my price. I don’t know anything about the environmental differences between spf so I won’t comment on that.
Would you mind elaborating on that? Is it that these people are in his YouTube comments, maybe on a subreddit? I never followed this guy, I’ve only seen probably less than 5 videos he’s made (likely only 2), one of which was this open source video.
Originally I avoided the guy because he was just a “loud is funny” let’s player, then I heard he said the N word, and i had heard people trying to get him to be the #1 YouTube channel over some music conglomerate.
In any case, while you can do things to attract certain people, I’m not sure how much control you have over your community, which is why I’m asking.
