100 addresses? That's insane. That's like going to the bank and them giving you 100 checking account numbers.

Addresses are single-use payment identifiers.
Using the same one more than once is a security and privacy vulnerability.
OK, so how do you get a mass amount of people to donate bitcoins to you securely??
Put out 100 different ads with different addresses?!? Seriously?
