Discord Censorship
I don't know what kind of Commie BS the developers over at Raid are used to, but there's such thing as freedom of speech. Removing the emojis - as petty as you think they might be and how little you like them - are a way for the players to react in a fashion that they deem fit.
Don't like them giving you middle fingers? Don't make moves that make people unhappy.
Don't like the poop emojis? Figure out why the game is going down and has to be reloaded multiple times a day.
Making it so players can only react with hearts is also incredibly petty and tantamount to rubbing in our faces that we're powerless... on Discord.
This also further reinforces the notion that Raid caters to new players only, to get them to download and spend $20 or $40 before they move on, and not to the dolphins or casual spenders who enjoy the game for what it is.
There is a list a few miles long of things that need to be addressed and fixed: I'm not sure where emojis rank on the list.
Between Dracogate, the hacking, Arena, the lies, Darth Micro, and everything else, removing emojis is simply going to exacerbate the problem. I'm not sure what you were expecting but I can only see the game further dropping below its now 4* status.
Please wrangle in your Community Managers.
P.S. If ya'll aren't familiar with it, I would highly recommend looking up the Streisand Effect. It might help to explain why what you and the Community Managers are doing is having the opposite effect.
