I would LOVE to hear feedback on this... We have an overflow of bikes, some of which have been rusty and broken for years (but still chained to the racks). We recently purchased a new, larger, rack. When we install it, we plan to send a notice to everyone that says all bikes have to be moved to the new rack, and any left on the old rack after x days will be thrown out. We also wanted to add a tracking system for the bikes, so we can monitor if someone moves out and leaves their bike, we can get rid of it. Not sure the best way to implement it would be, so I'd love to hear ideas!!
