So where is the line?
I mean this is just sugestive more than anything else right?
A girl eating a popsicle is fine, thats a natural thing for a girl to do, a girl sucking on a dick shaped popsicle is not.
Anything sexual thats blatently been forced by an adult is loli, clothed is less to worry about, any bare genitals (vagina, chest, ass) showing is a big no no, even when the art depicts a child doing natural things, it will get you banned.
Less clothed art of a child can be ok, example art of a girl swimming in a full swim suit is fine, however a girl with her legs spread showing off her cameltoe is not, or bent over provocatively etc.
A piece of art with a child in lingerie is not ok because lingerie is sexual and sexualisation of an under 18 art subject is a no no in some countries, ergo its a no no with us.
Basically just use your common sence, in some countries art is treated as real as photographs now, therefore ask yourself is it ok if I uploaded a photo of this.
Imagine an old fart is looking at the art your uploading of a clothed child, if they would consider it a kid doing normal kid things and perfectly natural and decent, then it's probbaly ok, if they would frown and think it innapropriate, it's likely to be an image we'd just remove it and maybe warn you depending on how bad it was, again art of a nude or partialy nude minor will most likely lead to a ban.
I'm sure slayerduck will correct me if anything stated is not in line with booru rules :)
