I dont usually make lists of Do's and Dont's these days but, I just wanted to point out to those on how my characters would be used in arts made by others.
If ya feature them in any art, just make sure you dont feature them in any underaged bad NSFW stuff or any sickening sex related stuff, and do not have them in these followings that you see in many other arts;
getting into trouble.
Pranked
Time-outs
Grounding
Punishments
Scolding
Getting Yelled at
Framing someone
threatened
getting caught by parents
AND most importantly of all, NO SPANKING! As you should all know, I've NEVER EVER been a fan of spanking. EVER! I HATE Spanking. It Just feels WRONG for me! Especially seeing someone getting spanked. (Pardon my rudeness)

As for SFW arts, like playing toys and games, drawing, or anything cute as long as it' doesn't feature the things from the list above, then it's alright. Simple Diaper usage (wet & messy) is okay as well just no hyperwetting or hypermessing.

Thank you for your time reading this. I hope you understand.
