Hi there,
If people wrote a message like that : "HI THERe", it won't be filtered
That's why I rewrote your function (not so good, i'm a bit noob with lua).
This should hide message if less than 20% char are caps.
Here's the code :

local function bottleCaps(_, _, msg, ...)
    -- prevent all caps from showing in the chatframes
    if db.ignore then
        local tmp = msg
        local value
        local a = true
        for i = 65, 90 do
            a = true
            while(a == true) do
                value = string.find(tmp, string.char(i))
                if(value == nil) then
                    a = false
                else
                    if(value == 1) then
                        tmp = tmp:sub(2)
                    else
                        tmp = tmp:sub(1, value - 1)..tmp:sub(value + 1)
                    end
                end
            end
        end
        local ratio = tonumber(string.len(tmp)) / tonumber(string.len(msg))
        if(ratio < 0.2) then
            return true
        else
            return false, msg, ...
        end

    end

    --~ if db.ignore and msg == msg:upper() then
        --~ return true
    --~ end

    if db.verbose or msg == msg:upper() then
        -- Verbose Mode = all chat becomes lower case, regardless of original case
        -- else all ALL CAPS CHAT becomes lower case
        msg = msg:lower()

        -- Fix links
        msg = msg:gsub("|hitem", "|Hitem")
        msg = msg:gsub("|hquest", "|Hquest")
        msg = msg:gsub("|hspell", "|Hspell")
        msg = msg:gsub("|htalent", "|Htalent")
        msg = msg:gsub("|hachievement", "|Hachievement")
        msg = msg:gsub("|htrade", "|Htrade")
        msg = msg:gsub("|henchant", "|Henchant")
        msg = msg:gsub("|hglyph", "|Hglyph")
        msg = msg:gsub("|hurl", "|Hurl") -- website links created by Chatter, Prat etc.

        return false, msg, ...
    end
end
