I spent a few quiet months on Toyhou.se, and my experience degraded very quickly over this time. I would not suggest anyone ever sign up for this site if they can get a code, if you have any integrity whatsoever as a creator.
First of all, this site does not promote creative freedom. If the large, toxic community does not agree with something you write, you will be harassed incessantly.
I was personally told I was "suspicious" for venting often about a topic close to my heart and that affects me in real life: being short and often compared to a child for genetics that I CANNOT CHANGE (except, in some rare cases, with extremely expensive and invasive surgery that I have no interest in taking part in). I have been on the internet since the advent of AOL, I guarantee I am older than most of the people on Toyhou.se (especially given the childish way they react to anything they dislike), and I can and will live my life as an adult because I am, legally, an adult, and have been for a while. But because I am short (genetics), have small hands and feet (genetics), like to wear clothing that hides my body (personal choice to combat social anxiety as well as comforting because I'm autism spectrum) - anyone who interacts with me is somehow a pedophile, and I am a pedophile for defending people with similar genetics as well as characters that have these traits but are legally adults. This is offensive to a staggering degree.
Make a neocities or something and store your characters there. Do not give Toyhou.se the money they do not deserve - mods do nothing about this system where the forums are a toxic mess of people shrieking "CP" at things that are not and getting the entire site to defend their asinine views.
