This issue is already quite widely publicized and quite frankly “we’re handling it and removing this” is a much more harmful response than I would hope to see. Especially as the admins of that instance have not yet upgraded the frontend version to apply the urgent fix.
It’s not like this was a confidential bug fix, this is a zero day being actively exploited. Please be more cooperative and open regarding these issues in your own administration if you’re hosting an instance. 🙏
I feel like it’s up for discussion here and you very well may stand by the response there, but IMO with how prevalent this issue is, a specific response of “we’ve disabled custom emoji” or “we’re upgrading to 0.18.2-rc.1 today” would have been more constructive and reassuring to users. Removal of the question and lack of details gives me a lot less confidence that the issue and fix are understood and doesn’t leave any room for that discussion.
