I was really into reddit four or five years ago, I think around when no-fap started to take off. As I understood it, it was a support group for actual porn/masturbation addicts, the ones who were losing relationships because it was fucking up their sex drive and losing their jobs because they kept jerking off in the stockroom. Because the internet in general and reddit in particular really like small optimistic soundbites, I guess the message warped into "not masturbating makes you a better man!"
There's a reasonable idea somewhere at the core, but of course once you start talking to them and joining in with their shit, it gets extra culty and delusional. That's what I really don't get. I can see someone reading about how someone's life improved when they started watching less porn, and maybe decides not to jerk it for a week or two, but how do they not start reading these posts and realise that's not what it's really about?
edit: Also, in regard to the slightly different scores, reddit fuzzes displayed votes a little. I don't really get how it works, but apparently hiding the exact score is useful to prevent spammers and vote manipulators, because their fake internet score system is sacred.
