>Using their lingo in any capacity, unless further heavily justifying context is present (I guess)

No, we don't care that much about slang words from nu-internet. We care more about stuff meant to troll other users for self enjoyment. If some slang is only used for the purpose of enraging others, then it's b&. Though I can't think of any off the top of my head. Greentext stories are also banned.

>Reposting tiktoks, or other mainstream things if too obnoxious (I think)

My litmus test for this is if it doesn't give me a boner, it's gay and deserves to be deleted. Unless it's a hot girl swinging her big tits like a pendulum, get it outta here.
But that's just how I deal with it.

>Flame wars and ragebaits

This is covered by Rule 8.

I don't have enough time to go thru all of this, so other staff-san can engage with this.
