Why it's not new user friendly:
1) Implies hierarchy- It's fine if the user themselves made the post because it can easily be taken as a e-peen egotistical joke but this was made by another user for a single specific user. There is only one of these threads. It's basically saying: Fuck all the other users, this is the only one who's worthy of respect. they're not I mean, coming from people who's been here for a while, yeah we get it's just normal CL attitude to pull shit like that but remember that new users probably don't have that mindset.
2) It's not a warning- It's really not. It's basically telling you how you should act or else you deserve and should expect to be harassed. No. No one deserves or should expect to get harassed. I mean, yeah, you're on the interwebs and you should probably prepare yourself for it, but this is basically akin to saying slut-shaming women is fine. They deserve it because they dress a certain way that they feel comfortable in. It's pretty much like saying: well, yeah, you wouldn't have gotten raped if you didn't do X.
It's the same shit.
3) Respect to gain respect is not applied- Look at the thread. It's not saying that respect is reciprocal. It's basically saying only you should respect Kirn but he doesn't have to respect you for shit. Kinda ties in with hierarchy point.
My point is, this thread basically brings misconceptions to new users and pretty much throws them on the bottom of the shitpile.
They shouldn't be told to act a certain way just to cater to someone. No one should. And should someone be a dick to the person, they should feel the obligation to send in a complaint without having someone to say "well, a thread warned you not to act like that around X". That's fucked up and just gives a bad impression to the community in whole.
