The Lemon Games was removed because the author was UNDERAGE AT TIME OF POSTING. This site clearly states the users must be 18 years of age and OLDER. Not YOUNGER. Whether or not an author chooses to repost work after it's been deleted for that reason , is entirely up to the author, provided he or she is 18 years of age or older when they do this. There is no room for negotiation or wiggle room on this one.
As to the story adoption, that's an EASY process. As stated above, we get reports years after the fact. That's right YEARS. When the author in question cannot provide the proof, or we can't find it, the story has to go, as unauthorized continuations, adoptions and sequels are in fact plagiarism. Most authors when approached will give a VERY clear answer to this, of yes or no when approached (whether by us after the fact, or the user who intends to do this). Sorry, if the author of the original work that's been 'adopted' without permission says no, that means no. It doesn't mean maybe, or "I'll think about it". That's simple enough, yes?
