    I am pleased to see that Y! acknowledged that the Blocked Continents feature’s accuracy is not guaranteed. There is a paper that explains the limits of geotargeting here.

    IP address exclusion can be effective, but it must be carefully monitored. IP address blocks change hands when companies merge and/or sell off assets, so what may be a source of fraudulent traffic now may be a source of legitimate (and profitable!) traffic a few months later.
