Humans get emotional when people talk chite about them. That's a fact. Human get emotional when they don't get the respect they think (or actually do) they deserve. That's also a fact. Yes, different people will be affected by those emotions at different levels, and in different ways. Because humans are very, very diverse. Not everyone gets upset over internet things (or at least not to the point where it becomes noticeable), but there are those who do feel bad about things people say/do over the internet. Does that make them weak? No. Would you call someone weak if they screamed/yelped when they accidentally had a needle jabbed/stabbed into their arm just because you've seen people who don't react at all to that kind of pain? If you said yes to that, then you and I are very, very different. A lot of people consider emotional pain and physical pain to be completely different. In some ways they are, yes, very different. But in other ways they are very, very similar.
Can we all just move past the people who hurt us?... Not always. Yeah, we can take steps to avoid them. We can block them and all of their subaccounts. We can block them on skype. We can avoid threads that they're in or flat out avoid the faction(s) they're in. That can, understandably, feel like it makes one miss out on a lot. What does someone do at that point? Do they keep avoiding the person/people who hurt them, or do they stop avoiding them completely, just so that they can be involved with some of the bigger things? Really, what you do depends on who you are, who is bugging you (or who bugged you), and how involved said person is in what you want to be involved with. Sometimes you have to do your best to say 'hey, this person doesn't make me comfortable. i can't avoid them entirely, but i can pay them less attention than i used to'. Other times, well, you really do have to keep avoiding them. Even if that means you miss out on some stuff.
Your personal health, mental and physical, will always be more important than in-depth, extended alternate universe fanfiction with original characters. That's something I'm really good at forgetting. If someone does really bother you, then you gotta do something about it. Sometimes trying to talk to them or their boss/FA/RPJ/SA (site admin) won't cut it. So, yeah, unfortunately there will be times where you gotta cut people off. But don't let anyone tell you that you're silly or weak for doing that. Because guess what? You, like them, are either a human or an extremely advanced AI. If you're the former, than you have feelings. Feelings are legitimate, understandable, real things. And they're important. Now, if you're the latter, then I have to ask why your creators thought a Star Wars roleplaying site was a good place for you to learn?... Unless you're doing this without permission, or you've gone rogue. In that case... I'll just pretend that you aren't an AI.
If this, or any other invasion, makes you feel bad, then take a break. If it makes you angry, take a break. If you feel the need to go off on another writer, take a break. And if you find yourself on the receiving end of anger, step back, take a breath, and proceed with caution, or don't proceed at all. Angry people are difficult to work with. If the person/people you're having trouble with are consistently angry or aggressive, it's best to either ask them to slow down (politely and carefully, because, as mentioned, they probably won't want to hear it) or to go to someone else for help. At the end of the day, if they still give you chite, then put them on your list of people to keep an eye out for. Do your best to avoid interactions with them, or at least interactions similar to the one that caused the initial trouble.
TL;DR: Emotions are things people experience. They are valid, regardless of their cause, and people will act on them, even if their actions seemingly 'defy logic'. We're (probably) all human, therefore we should do our best to understand each other, even if other people don't do what we would do in a given situation. Lastly: Take care of yourself. Always.
Just my 2.5 cents.
