In case the potential reasons aren't obvious, I think the mod is inappropriate for multiple reasons.
- I personally think a mod with a name like this has no place on an official Factorio site, where presumably Wube wants all current and potential players to feel welcome. If someone considering buying Factorio wanted to see what kinds of mods it had and saw this, I couldn't blame them for being dissuaded from purchasing. In case it's not clear why the name bothers me, the word "gay", when used flippantly like this, is seen by many people as a slur unless the context clearly establishes otherwise.
- The name does not seem to come anywhere near describing what the mod does (not that I have installed it to find out), and at a minimum does not match the mod's description. I realize that mod names can be creative and don't have to be a literal description, but I think this one is a clear case of abuse.
- Based on the description, it appears to be an exact duplicate of another mod.
