Obtains email addresses from subscribers to mailinglists of clients of ymlp.com. This is 73 lines of proof-of-concept-Java (7) source code (1 file) that does 10 http requests to ymlp.com to obtain one email-address.
The emailaddress is printed to stdout along with logging information. This is repeated in a while loop. Your requests are throttled by ymlp.com. This program will perform about 900 requests per hour (single PC) and thus obtain about 90 unique email addresses per hour. It does so in a pseudorandom way to obtain different emailaddresses in different runs, but the starting point is always the same, so you might obtain many non-unique addresses in different runs. But you can program in other starting points.
