A kick results in a temporary ban, they're the same thing - it lasts for 1 hour after which you will be able to rejoin the FC.
We always give a 30-second warning before performing lobby sweeps so those on the Companion App have time to make themselves known and avoid getting kicked, and those in the lobby have time to join a P2P world.
Sorry to hear that you were caught up in the lobby sweep, however my only suggestion for next time would be to keep an eye on the chat while you're on Companion/in lobby so you can avoid the same thing happening in future.
