Today I learned that comments that do not violate any rules can be removed from the site.
What happened: the animator posted an animation and in the description indicated that "this is my first animation". In response I wrote "it does not look like your first animation". In response, my reply garnered 9 negative votes in a couple hours and was deleted the morning after. Wow. No criticism, no negativity, but the users didn't like it. Looks like e621 has a unique system: if you don't suck the artist's **s, your comments are deleted.
It's scary to imagine what it would be like to be a person who even slightly doubts the godhood of artists and makes even the slightest remark. Probably such a user will be blocked for life ...idk
I am against the voting system - every opinion is IMPORTANT. And if the artist can not withstand criticism - he is not worthy and praise.
But notice, in my case, there wasn't even any criticism! Bravo
