Even without click-throughs. Comcast Business routers keep a log of every MAC that's ever connected wirelessly. Granted I think it's a bug as it causes the MAC whitelisting page to take like a minute to load. Even my Mikrotik at home logs MACs by default. The log is small and not persisted, but log entries definitely stick around a few days. Don't count on your MAC not being logged.
