So I think they're trying to say that cunny is a lolicon term, and cute+funny can also be shortened to cunny.
Which I guess I can say is interesting and might actually be something that group of people might use as cover?
At the same time: wow this really feels like a stretch, especially somehow saying the community tags are Steam's fault. I mean it's gamingcirclejerk so maybe it's meant to be sarcastic? But that's not how it reads to me even in that context.
