You DID break the rules. You took someone else's work, modified it somewhat, and presented it as your own. I don't know the rules there -- but, at a bare minimum, I would think that just maybe they expected you to get permission before rewriting someone else's work and presenting it as your own. Again -- failing to understand this suggests deeper issues than you understand.
I did not present it as my own. I clearly typed that it was the remake of another story. And I don't understand why, after they warned me and locked the thread and I did not react, a few days later, without me having remade any other stories, they remembered that again and banned me for plagiarism.
And, another time, on a forum, I was banned for two weeks, but, after the end of the two weeks, when I tried to login, I saw the perma ban message. Then why didn't they perma ban me in the first place? Why did they made me believe it would be over in two weeks?
I consider these erratic changes of behaviour inexplicable. But maybe they are totally explicable among 'normal people', maybe they are part of some behavioral patterns among normal people that are so obviously right and logical that everybody is expected to know, so the fact that I don't know them means that I am so stupid that there is no need to even bother explaining them to me, which is why they never replied to my appeals and even my parents, when I was little and got mad at me and spanked me and I was like 'what did I do', they looked at me with contempt and answered 'if you still haven't understood what you have done, you are brainless, please don't talk to me' and, when I was about to ask them again, they would yell 'shut up, don't talk at all.'
