Secondly, no, DK is not respectful and polite. This is not a lie, it's the truth. Just because you are unwilling to believe it doesn't make it a lie. Does she try to be respectful and polite towards a small minority of people? Sure. But that doesn't make her respectful or polite as a general character trait. She is quite probably the most hostile and abrasive character that I have seen in EVE RP, and considering the general demeanor of most other capsuleers that's saying something.
Can you blame other characters for "starting it"? I suppose. I can't speak from personal experience since I wasn't around when DK was new and still establishing herself. But the key to being an actually respectful and polite character is that they are able to ignore attacks against them in favor of maintaining that respectability; it means they don't fight fire with fire. Diana does not do this. She takes every attack personally, and responds with equal and often superior force. This in turn prompts other characters to up their game, and so on and so forth it becomes a vicious cycle. If DK wants that hostility to end, then she's going to have to be the one to take the high road and learn to let attacks roll off her shoulders and refuse to respond with insults of her own. She's going to have to treat even the people who are opposed to her with respect if she wants to get anywhere.
She is indeed very aggressive character, and as for being polite towards small minority - it is generally everyone she meets, before they start attack her
As for blaming about starting it.. well, it isn't actual blame. It is DK's trait. She is very conflict-inspiring character, although she never starts conflict herself. But when someone starts it against her, she willingly accepts it and... escalates
It is a character to fight, to conflict, to make enemies and wreak havoc, and sometimes I am rather disappointed, when instead of a violence character gets... rather unusual interaction
She is also rather flexible character and can cease conflict, if other party wishes so. Otherwise, she will never do it herself and will just continue escalating.
In short, I could describe her best as "She is looking for trouble".
Now, I will say that this is not a requirement for RP, since as I've said before IC conflict is a good thing and it's okay if characters don't like each other and are hostile with each other. But this is a lesson that is just as important for OOC relations, too. Far more important there, actually. Maybe you consider yourself the victim here, but that doesn't matter. Responding with hostility won't help your case and won't make people vouch for you. More often, it will make those of us who do try to stand up for you throw up our hands in frustration because you just go and run back into the fire. I don't support the ban, but if you want anything to get resolved you need to recognize that it's a two-way-street and that there needs to be some give-and-take. Don't dismiss criticism and advice out of hand.
Well, character traits aside, the topic was about the ban without reason.
There is a thing, that can be considered as criticism and advice.
For example, when people say "Diana, calling gallentes filth is bad, stop it, or you be muted".
Diana: But gallentes are filth!
Mod: MUTED.
This is pretty much Diana's behavior. She asks for trouble - she gets it. She knows she is doing something wrong, she knows consequences, yet she continues knowing the result.
What happened now:
Diana talks in summit, Diana gets banned. Diana has no idea what she said wrong.
She wasn't asked to stop doing something. She wasn't even notified what she said wrong.
She just was banned.
For criticism, you say something like, this is bad, you should not do this (maybe tell why, but it is not really necessary - just at least to know how to behave to not get banned).
Advice? There was none.
Just people saying Diana is bad, Diana is awful, Diana is terrible.. How is this criticism?
Nobody said yet what exactly she said wrong for the ban.And that's the problem.
