The only time I've ever had a filter leak, is when I re-installed one (on a race car that needed oil cooler adapter maintenance) . I'm 100% sure the seal had compressed initially, and sealed perfectly. But the second time around, the seal was hard and no amount of torque would give a perfect seal.
It's good to know that filters can be left on through multiple oil changes on most modern engines. Some manufacturers actually recommend this practice. Mobil 1 rates their filters at 20,000 miles.
