I will! Yes, I completely resonate with you especially since I have written my fic for 6 months while I was going through some hard times and did it with a lot of passion and then this person read it, commented, then started her own Thrandiel fix with my dialogue lines, exact wording etc...she deleted all of our conversation later on so that people don't see it. And because she's one of the admins on that website I found out she has been giving herself fake appreciation comments on her fic and has full protection, I was told she is allowed to take ideas from other writes on AO3...I think all people should know this about AO3.
In any case, lots of love and don't worry, the fakes will be revealed
