Help needed with Regex phrasing.

So I am trying to use a regex based word censor to block LMAOBoX users on my TF2 server from being able to spam the chat by blocking out the phrase "LMAOBox". I have SMAC on the server to catch the cheaters, this is just to prevent the chat spam.

Here's the problem I need help with - I want to allow both "LMAO" and "Box" (as neither of them on their own are offensive) but I can't figure how to block the combined "Lmaobox" without also blocking the seperate "LMAO" and "Box".

This is what I was using before:
And I tried:
Neither worked.

I have been using this page for testing, but as I'm pretty new to using regex I can't figure out how I need to phase it correctly. Is there anyone out there familiar with Regex who could help solve this?

Solved thanks to /u/logiasin on Reddit.

If anyone else want to block 'LMAOBoX' but not the separate 'LMAO' and 'Box' via Regex, use this:

You say that, but SMAC is taking care of the cheaters and the Regex word filter plugin is stopping the spam.

0 problems now.
