As someone who voted in their GOTY poll, I'm glad that they saw something suspicious and did something about it. I would not like the actions of a few idiots messing up the list.
This isn't about whether the game is an eroge, because there are actual eroges that have not only gotten coverage but -praise- on the site. The issue is with it clearly being someone pranking them with a game that I have never heard anyone on Kotaku mention once before now. It's so clearly a troll, and it obviously shouldn't be in the top 10. Kotaku did the right thing by acknowledging it and then going with a final list without it.
