Ways not to lock your bike

the white mtb in the back has a decent lock and went through the front (even though it's just a cable) but neglects the rear - my bet it has qr as well. but with a freecycle right next to it, i'd say it'll be rather save.

maybe they both belong to the same guy and he is using the "distract the thieves with an unlocked bike next to my locked bike" technique. expensive method, and not very effective.
