Is it possible to be kicked from the game automatically when something is said in chat? [closed]

To check what the player chats, we use the Chatted event

game:GetService("Players").PlayerAdded:Connect(function(player)
    player.Chatted:Connect(function(msg)
        -- Code Here
    end)
end)

Next, if you're looking for specific words, you need to break the message up into separate words with string.gmatch ["(%S+)" checks for spaces]

for cease in string.gmatch(string.lower(msg), "(%S+)") do
    -- Code Here
end

To check for phrases, simply iterate over the message with string.match to look for a set of words which matches our censor

if string.match(string.lower(msg), chatted, 1) then
    -- Code Here
end

Finally, if the censor returned a true value (the player said something we dont want them to say) we kick them

player:Kick("Inappropriate Language")

Example Server Script

local censor1 = {""} -- Words
local censor2 = {""} -- Phrases

game:GetService("Players").PlayerAdded:Connect(function(player)
    player.Chatted:Connect(function(msg)
        local check = false
        for index, chatted in pairs(censor1) do
            for cease in string.gmatch(string.lower(msg), "(%S+)") do
                if cease == chatted then
                    check = true
                end
            end
        end

        for index, chatted in pairs(censor2) do
            if string.match(string.lower(msg), chatted, 1) then
                check = true
            end
        end

        if check == true then
            player:Kick("Inappropriate Language")
        end
    end)
end)

In the above example, all words in the censor arrays should be lowercase (since we check with string.lower()
