Good question hmm, I think its just a different strategy with phone contacts A data broker primarily wants the social graph to make a user profile with a phone number, to show ads later on. Those people wont typically be texting or calling with spam and ads, theyll just match the number and contacts up with information shared in other apps so that ads in your normal internet browser or ad-include app use are more targeted so if an erroneous contact never logs in thats of no consequence to them, so searching to exclude numbers would be less interesting and less likely than with just sanitizing emails
