I have been researching this ever since it was announced.
For those that dont know what it is. Here is some background. Google never intended to buy Digg. They just tricked Digg by starting a takeover bid to get their hands on all relevant information via the due diligence process. Then once they had that info, they were just like "nah, that's OK. We've got what we wanted without paying $100 Million. Have a good life!"
This feature is being dubed the "Google Hot or Not Buttons."
As you can see from this screenshot above in 1st post, now two buttons appear to either promote or remove a result.
It's probably too early to start trying to abuse this feature. That's because it's unlikely they will use this initial data to rank results so at the moment it only affects your own account and profile search data. There has been talks of using it for real search data and indexing but it has to be up to standard.
I would say, don't break it til we're sure it's being used for real time search ranking and indexing and then it will be worth breaking.
Then, of course, you're gonna want to get to exploiting on a major scale.
Here are some creative ideas for you all to think about and research:
1) Malware is the most obvious attack method, but that's likely to be on the illegal side.
2) Creating fake profiles - although that may prove difficult if Google is using email usage as a metrics for verifying user authenticity.
3) IP Changing & Clicking your results - I don't think it will benefit you to search for every term your sites rank for and promote every result; I have faith that Google isn't that stupid in 2008. That method will probably not work, may be detrimental to your "user rep", and will probably be a dead end that will have you wasting days on something that is unlikely to bear any fruit.
My advice is to take some time to think of how to best attack this new feature. No need to jump in, as your experiments may not show results even if those same experiments might work few months from now.
You want to abuse the Google Hot or Not Buttons?
Yes, me too. But be patience dont fu*k it up so early in the begining stages wait to full release otherwise they just catch on too soon.
I have my own coplied data/research on this including results, methods and techniques. Just research it for now they when you have a certain made method then exploit it on them releasing it otherwise you just throwing it down the drain by getting greedy, overdoing it and you will be shutdown in an instance and Google with patch the loopholes up.
Just my 2pence.
