Y’all remember what we said in our Guidelines for New Authors? Trolls like free things. In particular, trolls like free books just so they can hate on them. Or even worse, they write nasty reviews on (potentially free) books by authors they believe to be badly behaving.
Case in point:
If any of you see this kind of thing, please report it. Trolls shouldn’t be allowed to steal a book just to post a nasty review because the author is on their hit list. This should never be allowed to happen.
