For years I've used e621 as a platform to... enjoy various furry art and artists. They have a great and extensive tag system for the website that makes it easy to navigate and find what you want.
Problem is if you want to upload art. Recently, I went to upload art of my furry character, and I will admit that I'm not as skilled as a lot of the artists on there, but I'm not terrible either. After submitting several images I made, I was really confused as to why the moderators were taking at least a week to approve my images. Most recently, I went to check again, and they had all been deleted. I had never recieved any kind of notification or message as to why, and I wouldn't even know if I hadn't been using one of my images as my profile image.
Turns out my work "Does not meet minimum quality standard". What? No where on the site are 'minimum quality standards' defined! Not only does this really discourage new artists who want to make an audience and receive feedback, but it also shows how gated and shady they are. If my icon hadn't been deleted, I would have never known why my work was rejected.
