@Basil-Godevenos To me, most of those would be acceptable for kids, I grew up on harsh stuff and was taught to separate fantasy from reality and such.. Some parents might not like some of those.
Tapas would be the best platform for kids work as it is purely comics, and the mature section is separated. Instagram is a cesspool of everything, not as bad as twitter though. I could see parents installing tapas as it's pretty safe viewing. Could always post on other sites and link to tapas to try and funnel traffic.
