I recently wrote a feedback (on the feedback.minecraft.net page) about Crimson and Warped Stem textures. I pointed out a way to improve it. And... It got removed because apparently it looked like a bug report... Are you using bots? Do I have to write in caps that it is a feedback and not a bug report? It was a good feedback... I saved it of course but I am not sure if there is a point to resubmit it. This bug removes all motivation to write feedback.
My removed feedback was on this page if that helps...
There is a feedback button in the feedback site, try contacting the admins there to reopen the post
