This is where a separate perv persona for online ... whatever ... comes in handy. It's why I would never buy such a game on Steam(or at all, but that's just me, and far from advice I would give).
Just give an answer in-character, not an IRL one.
Yes, I may play a your standard murder-hobo in games, but I would still like to be able to do a guest appearance on my kids' or a friend's Twitch/whatever streams without some one digging and sharing with them that I had collected a trophy/achievement in Murder Harem: Furry's Vore Safari Edition, or even the vanilla crap I am actually even slightly into.
There be no blasphemy or deception like using a plastic banana rather than whatever random banana they have at your local store.
