Is it safe for me to play this kind of video game?

I'm addicted to an animal simulator video game as an adult. I got into it after the whole 'goat simulator' fad got me curious. It turns out that goat simulator is pay to play and I don't trust Google Play with my payment details, nor myself to know my spending limits. So I experimented with different animal simulators until I found an amazing RPG-style one with loads of different animals and a multi-player text-chat. I love that it's really wholesome and about nature, and the graphics are beautiful, and it contains no blood or gore or guns or violence or anything gritty, political or cynical.

The thing is, most of the users are kids. That doesn't bother me on a personal level because in my day job I work with kids so I'm used to it, and I'm basically just a big kid myself. Also, when all you see is a line of text you begin to forget after a while that they're even kids until their immaturity and atrocious grammar begin to grate on you. But I feel a sense of responsibility towards these kids, and am concerned for myself, too. Once or twice I did see things of a sexual nature being said in the chat - though it was a long time ago and I haven't seen it since. You can never know who is behind a smartphone screen in a game like that and I'm just hoping that if it was minors, they were just 2 frisky teenagers and not an adult and a minor. It's a child protection nightmare.

As regards myself though, my gut is asking me whether it's really safe from a legal perspective to be playing a game with a chat mode that is mostly used by children, when there are so many ways that that game COULD be used for predators to groom kids and it would be easy for anyone who found out I was playing it, to point fingers at me and accuse me of only playing it to groom kids.

My question to you is this: should I wean myself off my favourite game to 'cover my back' just because its main user base happens to be kids?
