You'll need to check the distance travelled in X time, that's basically the core idea. Also it's very important to respect server-side teleports, or client-side teleports (interior enter/exits, tuning garages, bugs, dying/spawning, lag, falling through the map, extreme vehicle speeds (eg for freeroam servers with boost function), etc).

It's quite a lot to do and prone for false detections if not done right.

For a start I would disable all default interior enter exits and replace them with a server-sided system to have full control over it.
Then hook SetPlayer/VehiclePos and update the last checked position with the target position, so that the server knows it is a legit teleport. Also add a delay to give the client some time to send the updated positions after a teleport (a few seconds for example).

I would also refrain from instant bans/kicks, but rather work with warnings and admin notifications so that players dont get banned for nothing in case it's not working 100% accurately.

I'm not sure if it is still up-to-date but it's certainly well done and you can take a look to get an idea of how it should work:

It lacks a few things, like actual checks if an interior teleport is valid, or vehicle speeds, surfing etc.
