But also maybe since we just got a new recommend qualifier added - Enabling conflicts to continue - maybe we can discuss some fun and not sucky ways to keep antagonism alive! I'm going to post my own opinions and I'd like to establish right here that I'm not intending to target anyone (especially not you, you scamp!).
We can avoid going too easy:
I remember when Galen's player and I first started playing on TI we were sort of surprised at how hard it was to play a struggling Freeman because of how easy money comes and how helpful everyone is. "Everyone too helpful" is not nearly the worst problem to have, but it does kinda gum up someone's character concept and deny them the sort of RP that they like (overcoming struggles). Especially if they looked at the big discrimination warnings in the chargen nanny list of races and still chose to play one of those races, for example.

We can also avoid going too hard:
The other thing that tends to throw a wrench in the works is when people crank up the law enforcement up to 11 over minor crimes, ostracize people, or make their characters unplayable for getting caught out trying to rock the boat at all. Reeves, for example, join the Reeves to participate in Reeve RP; if they scorch the earth over every pickpocket, no one's going to want to enable that side of the RP for them and they'll suddenly find themselves complaining of boredom!
I get that sometimes it's exciting because of our limited playerbase - when you see a crime mood or hear of something wicked, you jump on that RP hook and you ride it hard. But we (lawfuls) don't have to win every encounter - I've OOCly let mages go just because it would be boring and suck really hard if I'd caught them at that time; I got really excited once and brought a mage in after catching him wilderness evoking and just kind of felt crappy about it after. The ones I let go eventually got the pyre, but after much more satisfying stories with exciting resolutions. Just look at what happened with Jemven (log's in the fanfic section)! People put a lot of work into their characters, so please burn (literally or figuratively) responsibly. This game is very lawful-biased and we need to cherish our villains, our shitty furniture, and our manure smell.
We can forgive mistakes:
I can't entirely blame anyone for being too zealous in stamping out crime, corruption, self-serving behaviour, etc; I think there's a very real fear that if you ever "fail" it'll dog your character for ever - I've been on the receiving end of this. There's a lot of pressure to be perfect, but perfect is super bland. The best thing we can do is try to recall that thanks to time compression, our characters will at any given moment have forgotten 4x as much as us, and things will stop stinging 4x as quickly for them. Blood feuds and grudges are great until you've barred all avenues for someone and effectively socially PK'd them; it's good to try to only keep feuds alive if they're creating RP and not stonewalling it. In improv, it's poor form to say "no" and leave your RP partner with no cues or direction to take. =) And if someone keeps giving second chances and engaging with an antagonist, don't hold it against them.
Also:
This is more a personal pet peeve, but it's uncomfortable sometimes when people make awkwardly sincere attempts to smack each other down or hurt a character's feelings, and sometimes it does come across that they're trying to make the player so upset that they leave the game. I know OOC separation is expected, but we're still trying to make this a fun game and not miserable for anyone who wants to play with us (also a lot of the whole You Need To Not Have Feelings ARE YOU HARD ENOUGH TO PLAY TEXT GAMES ON THE INTERNET WITH US is dumb and part of the worst side of MUD culture and I hate it). My own personal rules are:
1. I try to let people know they can send me a tell if I need to tone down the uhh... creative insults, which was important as Haizea. I think I didn't do this well enough the first time, and it feels crappy to know anyone might have been up at night over it. We're pretty good at making people feel comfortable enough that they can hit "graphic" or say "I'm not having fun" - but a lot of times it's kind of nerve-wracking and embarrassing to admit you're uncomfortable. It's literally never hurt to check in with someone and make sure they were okay in a scene. Non-consent doesn't mean you have to put up with being miserable.
2. I try to keep it within the realm of "this wouldn't be totally awkward to watch on TV." - If TI were a movie playing on TV and I'd change the channel over what was going on in a scene, there's probably a better direction for me to take the RP in. You don't have to go full comicbook cartoonish like I like to do, but even in gritty dramas, needlessly gratuitous language and violence is just a sign of a poor writer. TRUST ME IM WRITE COMIC BOOK's FOR MY FOOD.
Anyway, I'm interested in hearing what others think - this is basically just a self-serving wishlist.
