I don't think many babies or kids use their moms phone. And even if that happens, many kids will not search anime, as soon as they reach the play store.
Also, many kids would have to see it on the popular page, and i'm not even on the popular page and I still produce mature content not suitable for kids under the age of 12.,
suicide is not all about killing yourself or standing off a bridge. Some cases say suicidal people are depressed, Not killing themselves
(Edit if you try to prove me wrong by saying suicide is caused by depression, I already know that)
Also Many people may stop suicide because they may not be ready for heaven.
