Right now we have very little tools to curate our Custom Emoji experiences. We can barely do so on individual level, and just cannot do so on a community management level (even if someone throws up an unsavory custom emoji it is near impossible to identify said person in a room of 80). Things should be much more proactive than user reporting. I understand its near impossible to content filter avatars, but its also hard and takes time to upload an avatar. Content filtering pngs on the other hand should be simple, there are countless solutions for that. And if its not simple, then VRchat is not ready for Custom Emojis.
We need tools for community emoji management
We need image filtering
We need group and world control over custom emojis
We need a log system so we can see who throws what emoji
We need tools to help moderate your platform if you wont do it yourself
