Hidden SSIDs are generally much worse for privacy than non-hidden ones, since all stations (clients in 802.11 terminology) need to constantly go around yelling "hey, is SSID abc available?" while they're not connected to any SSID.
I was ultimately taking the piss, it'll be radical if someone actually did but I had no idea it caused wifi pollution from this.
