I have to go with Aries on this one: what LuminAbyss has admitted to here is fairly disturbing behaviour, nevernind that it involved no physical abuse. What is described in those accounts is textbook grooming behaviour and I have no problem with it being outed into the light of day--especially considering the man has openly admitted it happened. Indeed, not that his comfort level should at all be the focus here, but as someone who seems to have recognized what he had done was wrong, even he seems to agree that this is appropriate (though I don't doubt that he probably also wishes he had made amends long before it got to that point). And I certainly see absolutely nothing in those accounts that would suggest to me that this is all some sort of collection of lies manufactured to get both parties some attention, as has been suggested above. Indeed, given the reputation that is going to stick to LuminAbyss, probably for the rest of his life, as a result of all of this--with substantial consequences for both his professional and private life--it would be a pretty monumentally stupid way to try to get some attention.
Now I can't speak as to the motivation of the other parties in raising the issue at this time, but I can easily see the most likely explanation as being that this is something that has weighed on them for a long time and they were emboldened by the current wastershed moment the FGC is experiencing. Is it something that is going to be best addressed in this manner? Who can say? But I certainly feel that the woman in question here is well within her rights to have decided that this was the right course of action for her, and I think she deserves every benefit of the doubt as to having a good-faith intention in doing so, especially now that the man she accused has admitted to the veracity of her story.
