Ruby, you can't force people to accept you in their RP even if you think their reasons are unfair or wrong. Creating a call-out post (your "Announcement" post which I deleted) about another forumer is bullying and against the rules, and you're talking a lot about Skyfrost in a number of threads behind her back. It also seems like some of the reasons Skyfrost isn't accepting your OCs are due to misunderstanding, for example thinking "too much ice and venom" meant "too much ice and too much venom" which is honestly how I read it as well. Clearing this up respectfully with her or just moving on to a different RP is the way to go.
I'm going to give you a 24hr ban so you can collect youself, when you come back please be more respectful or decide that this particular RP is not one you need to join. There are plenty of RPs on the forums to be a part of if one isn't working for you.
