Server Crashing Animation Exploit

[AbiZinho (Abi)]

Maybe you can detect the frame rate and somehow reverse engineer it to locate the player?

If it effects all players, then no. This would also be highly likely to lead to false positives (as it’s not a good or reliable method to detect)

[chexburger (Bark)]

Yeah. It will need to be fixed by roblox assumably.

This has been previously reported as a bug in the Exploit Reports section (that New Members cannot view):
https://devforum.roblox.com/t/loadanimation-error-spamming/225109

To work around this, you could use the Humanoid.AnimationPlayed event to find out if a player is spamming animations on their own character. For invalid animations, you can use ScriptContext instead to detect whether someone is spamming animation error messages into client/server output:

Someone gave this example code on the Exploit Report to give you an idea:

On another topic

This should stop some of the more noobish exploiters. Just put it in a server script.

local Players = game:GetService("Players")

local bans = {}

local function isBanned(id)
    for _,v in next, bans do
        if v == id then
            return true
        end
    end
    
    return false
end

Players.PlayerAdded:connect(function(player)
    if isBanned(player.UserId) then
        player:Kick("Banned from server")
    end
    
    player.CharacterAdded:connect(function(character)
        character:WaitForChild("Humanoid").AnimationPlayed:connect(function(a)
            local id = a.Animation.AnimationId
            
            if id:len() >= 50 then
                table.insert(bans, id)
                
                spawn(function()
                    pcall(function()
                        player:Kick("Animation overflood")
                    end)
                end)
                
                
                player.Parent = nil
            end
        end)
    end)
end)
