Add a few to the list:
OOC spillover
1)
* X thoroughly defeats Y in a fight (without godmodding or anything like that)
* Y tells X: [you f***ing godmodder! f*** you! you can't m-f***ing do that!]
* X tells Y: [...eh? what?]
2)
* X insults Y (ICly)
* Y tells X: [f*** your mom!]
This is just plain bad. I understand being somewhat attached to a char, but don't fly off the handle OOCly over IC issues, it'll just make you look bad.
Not understanding a character
I will speak from personal experience here, Kaerli is by far and wide a better fighter than your average citizen (in fact, she should apply for that job opening with the Sunshine Squadron
. However, just because someone seems to be very strong and is beating you left, right, sideways, and upside down doesn't necessarily imply that the player behind him/her is a godmodder. You might just be taking the wrong approach to the job! (psst...yes, Kaerli is beatable, she traded injuries with Kanti, and is 0 and 2 going up against Alliva; don't forget about Marathal's freaknaut either xD
Also, the same thing holds true when it comes to personalities and behavior. Don't assume that a character is going to behave in a stereotypical manner either:
* X dangles a dead rat in front of Y's nose, expecting her to scream
* Y laughs mockingly, throwing her head back "Oh, and that's nothing...ever gotten into an actual battle before?"
Not accepting advice
1)
* X tells Y [hey, you might want to ask a GM for a name change
I mean...what sort of parent'd name their kid that?]
* Y tells X [go f*** yourself, and the GMs can do the same]
2)
* X: lolol
* Y tells X: [try using emotes and /me instead of smilies or chatspeak, you'll help the chatbox read and flow better that way
]
* X tells Y: [shut up nazi, this is just a game, you don't have the right to do that]
This is, sadly, one of those cases where /report is the only option you have.
This is also, sadly, more common than it ought to be.
