No use, they're after the Crumpet DNA on your bikes.
More seriously, the key thing is to think more about where to lock a bike (develop a feel for which places are insecure), and other things like locking technique. Locks are just passive, low-level defence—always over-hyped because people want to sell them to you, but as we've seen many times, no obstacle for determined thieves.
Some of this probably needs updating, but most of it still applies:

Anyone who clones that beast is welcome to deal with the consequences (constant demands for attention and treats).
I like to think I'm pretty savvy when it comes to locking up. I've yet to have a bike stolen so must be lucky and hopefully doing something right! Cynically, I just try and make my bike less attractive of a target than something else nearby by using a decent lock and leaving mine next to something posher/shinier (not hard).That link is a useful reminder though.

Very reassuring to see that all of the handful of places I leave my bike locked up seem to be theft hotspots. It might be time to upgrade my lock!
