No, it's pretty much all scummy.
I get that it's popular with young teens for the social media aspect and the fact that their school firewalls don't seem to block the site. I don't blame kids for using it when so much of the web is not built with them in mind.
But the person running the site is absolutely scummy.
The paid subscription costs $49 per year if you want access to Decker's other built in patterns and colors (which are free), color palettes they took off of lospec (which are free) and a tiny, tiny amount of cloud storage (which people probably already have for free).
The site uses generative AI all over the place including the AI-generated fake "pixel art" that they use as highlight images on the color palettes which just seems extra insulting to the real pixel artists they took the color palettes from. They even promoted an AI service as the top banner on the website before they got their subscription system set up.
And they don't allow users in the social media area to post the name "internetjanitor". The automated review that happens when people post there will not let the creator of wigglypaint's username be posted on their site.
I don't think they want to be a fun, honest social media site for wigglypaint enjoyers. I wish they did. I think they want to fool people and make sure that their community stays fooled so they can keep making money off of young artists.
