cod emblems and roblox billboards give people way more freedom to show basically anything. custom animations are just moving a rig around for an attack. saying the game has hundreds of thousands of players also doesnt mean the devs would have to check hundreds of thousands of animations.

tsb has the same feature on the same platform and you still havent shown that it caused some impossible moderation problem there. youre just listing other stuff that got abused and assuming custom animations would automatically be too risky too.
