Alright, kiddo, so you know how there are some drawings of people that are meant to look like kids, right? Well, some grown-ups like to look at those drawings, and they call them "loli". It's not okay for grown-ups to look at pictures of real kids in a bad way, because that's very dangerous and illegal. But looking at drawings of fake kids is still not okay, because it can make it harder for some grown-ups to understand that real kids should always be treated with respect and care.
Now, some people have made a database, which is like a big list, of lots and lots of those drawings. This is definitely not okay, because it's like a library of things that are not supposed to be looked at by grown-ups. It can also encourage more people to do bad things, which is definitely not a good thing.
So remember, kiddo, it's very important to always respect and care for real kids, and never look at things that are not okay for grown-ups to see!
