It would seem a whole new kind of AO3 reader/writer is emerging and it is becoming clear not everyone quite understands how the website community works. Here is some basic guidance on how most people expect you to go about using AO3 to keep this a fun community archive that funtions correctly:
I KNOW there's plenty more I missed but I'm trying to cover most of the basics that people seem to be struggling with.
I invite anyone to add to this, but please explain, don't berate.
People are so entitled in the comments damn like no you writer don’t have to put up with you being rude they wrote you entertainment for free
To the people in the notes who are insisting that they have the right to leave negative feedback on AO3:
What you’re not understanding is that fandom is not a service, it’s a community. I saw someone compare leaving a comment on AO3 to reviewing a product on Amazon - if you didn’t like the product, you’re going to say so. But fanworks are not products and you didn’t pay money for them. They were shared with you.
Leaving un-asked-for criticism in AO3 comments isn’t like reviewing a product you were disappointed with. It’s like going to a friend’s house when they’ve cooked a meal and telling them all the things that are wrong with the food. Sure, you can do it, but it’s rude as hell and they are probably not going to invite you to dinner again.
("Can you leave crit in comments” has been a debate as long as I’ve been in fandom, but 20 years ago the argument was “I’m helping the writer improve!” and not “I am a consumer with a right to complain.” Fandom has gotten more creepily capitalistic over the decades but jerks are evergreen, I guess.)
