I dropped out of Yahoo because I told them of IP addresses that were notorious for fraudulent clicks which were sending me regular traffic. I asked them to block them; they said no, they couldn't because the traffic may be genuine. I walked away. When they get professional staff who know the difference between an ISP and a proxy server I may consider doing business with them again but until then I'll deal with competent people instead.
