when writing fanfiction, its bound to happen that within the same community, many authors would come up with similar plots and ideas coming from the same foundation. Such are the examples like having an original character as the daughter of alicent and viserys, or bastard daughter of rhaenyra and harwin, or daemon and rhea's child. It happens, its normal, and as long as you make your plot/story your own, it's not an issue. it becomes a problem when you blatantly copy someone's writing.
i am not the best writer out there, i write corny stuff, i sometimes makes no sense and im incoherent, but at least i can say i don't plagiarize.
i have proof of the user @/eeunoiq plagiarizing my story. they had it on their reading list and they follow my other account. they currently have a story up with the first few paragraphs of the only chapter available being a copy of mine. The plot is not entirely the same, but the writing itself is far too similar to mine, with some sentences being almost the same with little tweaks.
I've blocked them already, so hopefully it wont go further, but i'll leave the link below for anyone who could possibly help me report it (or compare it to mine and see for yourself if it is in fact plagiarism.)
