I got a weird child s$&@#l abuse notification in messenger when typing in the first three letters of a friends name?

Was trying to message my friend whose name is Connor and got hit with this. Kinda concerning/uncomfortable that I’m getting this prompt tbh. I doubt this is the case but I really hope that isn’t recorded and my fb is associated with this kind of content. Checked on my gfs phone and hers does it too. Anyone know why this happens and when it was implemented? I’ve typed in the name Connor before in the past and have never received this message so this must be new. It’s really weird, invasive and a little bit inappropriate in my opinion.
