This! Whenever I play unpleasant characters I like to make it very clear in emotes that this guy sucks and that you’re welcome to act accordingly. Helps minimize the impression of OOC bias and improves the flow of the scene like you said.
“I’m way stronger than you.” - Could be a powercreep jerk you can’t reason with OOC, better write carefully.
“I’m way stronger than you”, he pompously boasts. - Seems like a fun guy you can keep jostling with, yippee!!
If they mrgl, they’re good by my books.
When their race rhymes with “Shot twelve” 
An open mind
The RP-character stereotypes with negative connotations are definitely out there, but I feel like it can sometimes be easy to fall into the trap of judging them at first glance. But, if you keep an open mind, you can sometimes come away surprised. I’ve definitely had my own moments where I thought, “Oh no, not one of those characters…” And sure, sometimes the concerns are valid. But other times? The players behind those characters bring unexpected depth, creativity, and effort. And I think that’s awesome.
That’s why, for me, one of the biggest green flags in RP is when people approach every encounter with an open mind and don’t try to diminish their own effort into an RP-encounter with said character, but treat them like they would any other character. To me, it says a lot when someone doesn’t immediately write others off, but instead gives the interaction a fair chance. It’s often not because those players are intentionally careless, but might simply be because they are new or inexperienced.
I generally like it when I can see the narrator’s distinct voice in third-person channels like /e. Yeah, it’s a show of sportsmanship where those interactions are antagonistic, but I also just appreciate the different writing styles of other RPers. Seen some really charming and memorable cases that have stuck with me.
Maybe an odd one but… creative swearing.
While im aware swearing IC is crass as it gets. I do not mean stringing F-bomb’s together to the tune of Baka Mitai impressive as that would be.
What I mean is if someone has taken the time to come up with a swear thats fitting for their race or background that doesnt need to be overly vulgar or unfitting for the setting. Like…Gallywix’s Gilded Gonads. Greymane’s hairy backside (the one that rhymes with parse aint allowed even if it rolls better.). Etc. Im sure someone else can do better. But i think its a greenflag coz hey they took the time to think up something fitting to their character and culture. I guess?
I love this, I wish there was more in universe related turns of phrase.
I remember for a while I used to refer to anyone who was untrustworthy as ‘being from Alterac’
There are so many nice green RP flags.
The best one naturally is if the player OOC is nice and patient. I think that’s obviously the most important one.
For me, it’s also a massive green flag when descriptions are kept short - maybe around three paragraphs, or less. It usually gives a clear enough impression of what the character is meant to look like, but also lets the reader fill any little gaps with their own imagination.
It is also a great green flag when people go a little out of their way to acknowledge things, such as - I’ve always liked how on Alliance people might instinctively spot Light priests or paladins and offer the proper greeting even in passing, or on Horde Farstriders and Blood Knights saluting each other and acknowledging each other’s rank even when they’ve never RPed before and just walk by one another. These are small details, but create a beautiful sense of immersion and community.
A green flag for me is people sharing the locations of toys or items that could be useful for RP.
Be it roguestones for channeling spells or lenses to create a beam. (I like to give these out if someone is emoting something and it seems useful, it can add to visuals nicely)
My personal favourite that Des often uses is “Speak of Sargeras and he shall appear.” Not an actual swear but still.
I love it when I’ve RPed with a stranger for 2+ hours and they whisper me thank you, as it is a time investment. Similarly if they RP a mean character or have some IC beef with my mage, and make sure OOC that it is solely just the character. Always remembering people who communicate well.
Also honestly? Creativity and unique touches. I love RPing with people who clearly love their character and put their heart into them, rather than bland cookie cutter character who feels like an NPC.
Also versatility in alts. I love it when I cannot tell that this was a person’s alt. Shows skill to be able to RP different concepts and characters well.

When people are really able to separate IC and OOC.
Means no unnecessary info about the person behind the screen in their currently, no passive aggressive or outright toxic comments in my whispers during or after potential conflict IC.
Just pure, unadulterated RP taken at face level.
Minimal TRPs that only contain essential fundamental info

There’s many things posted that resonate with me, but to add a couple more…
From another thread:
Knowing that your character(s) aren’t applicable for all events.
It’s sucky to miss out on roleplay but Aerilen has no business (or actual interest) in taking part in druidic celebrations in Moonglade or joining in on the Vulpera Basket Weavers meeting. As an example.
