There's at least one other address starting with "1PWo3JeB9jrGw" in the 71 range.
No matter how you search, people should reflect on this fact: there's a 50% chance you'd first find this other address, before actually finding the correct one, and way way ... way later after dealing with half of the other 395.000 unique addresses (plus or minus 2000) that match the first 1+9 base58 chars.
It's even worse if matching just the H160 bits for efficiency. The number of comparable H160s is 3 to 4 times higher than b58 matches, because a lot of those won't match the desired b58 pattern, even though they have lots of matching bits.
