asking.
Non-english: English commments are fine as long as you keep it simple enough.
On twitter specifically, do not quote retweet to make comments. Just comment directly on the image. And going further, if it's a JP artist, don't go "like" too many of their posts. They often block foreigners and overbearing people due to fear of stalking (which is a common problem). Quote retweeting is rude because it's usually used to talk shit about an image without notifying the original poster. That's why, if they see a qrt and its in a language they don't understand, they'll have to assume it's negative.
Children: Honestly I don't know why you would even bother because chances are they won't retain anything. Pretty much don't at all unless they ask for it, or are horribly misguided about becoming an artist. You'll still be rude but it'll save the kid. I don't think there's a specific age but I don't find it wise to interact with anyone below 18 online in general.
