If you really don't like explicit language, why don't you take it away?
Just fill in the words with *. Don't make it CAPS sensitive.
Of coarse, people will try to get around this. There always will be. It will make your life easier.
Keep in mind though, sometimes you may see someone say a minor bad word (i.e the "h" word or the "d" word, I don't feel like saying them) that aren't ban-able.
Also, Roblox will just get more mod bots.
If people can get around this, what's the point of the filter anyways?
I'd prefer a filter that filters out any word that isn't part of an admin constructed dictionary.
