How much sense does that make? Person that can't be hit properly because of their warping joins server. Gets kicked and told to fix their ping. They rejoin the server then according to you they should get banned for a whopping 5 minutes. Guess what happens after that 5 minutes? They rejoin the server and it happens all over again in the meanwhile making more work than needs to be done for any admin in the server. Instead I use common sense and make them think about why their ping (warping) isn't acceptable with a 10 minute to 1 hour or so timeout.
