I have been receiving too many weird calls at odd hours. So I have re-listed my phone number as an md5 hash. The orginal string was in the format xxx-xxx-xxxx. If you can decode it you can call it. Using google cached webpages would be cheating.

Example python code to "brute-force" my phone number

import hashlib, random
my_phone_num_hash = 'a7852454caf08e4e8de354677d41c36f'
to_phone = lambda x: x[:3] + '-' + x[3:6] + '-' + x[6:10]
try:
	while True:
		phone_num = to_phone(str(random.random())[2:])
		assert hashlib.md5(phone_num).hexdigest() != my_phone_num_hash
except AssertionError: print phone_num
