First off: Really thanks for all the work you and @bannedtags do.
I see a lot of people screaming at staff, which I get, they made a lot of weird decisions but to some degree this website has always still been functional and we always found a way around stuff. I worked Customer Service myself, so here's what helps because people have to scream at Apple! And any other company who tries to sanitize the internet, otherwise I'll soon have to read fanfics on P*rnh*b.
1. Delete the app, leave it a really bad review, air your frustration and then change to Desktop. But especially mention APPLE in your reviews.
1.1. Leave a bad review on the Apple
2. Chat with Apple Customer Service and tell them!
2.1. Go here, click "Apps & Features" -> "Topic is not listed" -> Write App Update is a joke or something in the text field -> You should get the Chat option.
2.2. Tell them what happened (CS probably is NOT aware, no one tells them shit), and why it is ridiculous, if words like "antis*mit*sm" (<- ridiculous!) really should be b*nned and ask why this doesn't apply to Twitter, Reddit or Facebook apps.
2.3. If they tell you are at the wrong place with them, ask them where to go with this. Ask them for an email address. So you can send your complain there.
2.4. If they tell you, they can't give you an email address, be that person and ask for a manager (politely!!!!). Everyone that's behind an advisor, can do more shit and escalate it further until it reaches people who actually have to say something.
2.5. Be nice to the person you talk to, they're just trying to get around and any case DON'T leave THEM a bad review. However this survey is phrased EVERY answer reflects on the advisor, NOT on the company. People can loose their jobs over bad surveys, even if it's NOT against them. DON'T. DO. THIS. (If there's JUST a textbox for one question, like leave a comment, leave a comment there!)
3. Here's the thing, if enough people do this, Customer Service has to act. They can't be spammed with 500 chat requests over this ONE issue a day, keeping them from working on everything they should work on, like broken phones. If enough people do it, they have to escalate it further because they see it's indeed a problem for people and that it reflects bad on the company.
4. Just leave bad reviews for Apple everywhere and mention this is why. You can't review the Apple App Store, I believe. However there are multiple Apple Apps you can review. Also Facebook, Twitter, Instagram. Just write it in the comments, tweet at them, whatever :)
5. Does it do something? Maybe, maybe not. Still better than just screaming at staff for this.
