you see, for telemarketers the 'easy' answer here to get them to permenently take your number off the list is to claim being a buisness.
my freshmen year at the WMU dorms, i was getting about 5-10 marketting calls per day. then i got pissed and started answering 'hello, dominoes pizza! may i take your order? we have a special running on 2 large pizzas 2 toppings and a 2 liter for $16.99...' is isaac there? or 'this is dominoes?... click'
within 2 weeks, i didnt have one more unsolicited call
its illegal for them to call buisnesses and cell phones here.
