What's almost as annoying as the multiple daily posts asking about incest content, are the posts attacking them. People who come here, and read the posts, on a regular basis know there isn't and won't be any incest in this game. Whether they like it or not, if they like the game, they should (and mostly do) accept that fact.
The people who jump in with "Any incest?" questions are usually new players... new lazy players who don't bother to read even the last few pages of the thread. Do they deserve to be attacked? Maybe... no, not really. Ignore them or post a quick answer, if no one else has. There's no reason for 3 or 4 people to respond with a variety of insults.
What could be allowed and discussed is possible 3rd party patches, fan fiction with incest, fan art showing the incest, etc., though those things would all be off topic and should be somewhere else.
What should be allowed are discussions of alternatives to incest. For example: possible storylines of mc-related characters having relationships with non-LI, non-mc-related characters falls within the scope of the story and would not be incest. Even relationships between Willow and Azel or Azel and Wendy are possible, since they are not related. Are those relationships likely? I don't know, probably not. Are they possible? Yes, 100%.
Again... I'm a fan of incest stories, but I understand that it won't happen in this game and I'm not asking for it.
