I think the tool could be quite useful.
On a side note, I really do wish there could be something done to rep related security and safety add-ons, WOT is just one of them. Sadly, new mods/admins to security programs also often bring in their own bias or personal views into things, and any number of actually safe and worthwhile websites get blocked or set as a "STOP" kind of warning in security suites.
Sadly, that same type of things even has on the iTunes store. Honestly, I think between the "freemium" i.e. it's free so long as you buy the in-app addons, and/or where actual paid apps that are garbage end up being rated and shown as the top of the list, due to employees or bot programs used in the hundreds or thousands to give something a top of the list 5 star rating. Likewise, often the reverse happens and an actual great app gets 1 star bottom of the pile reviews just by someone who makes a competing app/addon/program/game. I think Steve Jobs would be rolling in his grave if he knew just go sad the state of affairs are on the itunes store lately.
Unfortunately, it isn't just iTunes, its worldwide. Hell, even sites you used to be able to trust like Download.com, PC world, etc. just because their editor/reviews/tests/ etc. are only raving about 1 program while putting down another, just because of their own personal views or ratings and reviews that get posted due to company A paying them to promote their product while putting down company B's product.
As far as iTunes goes, thankfully (*crosses fingers* and hopes and prays this never happens) it's a simple point, click, delete for any offending trash app, and isn't a virus or spyware to ruin iOS.
For those that use an iPhone or iPad, no matter what "rave" 5-star review you see on there, all it takes is going to the developer's website to see if its in a foreign language, or just take a moment to look at the app release/update date next to the purchase button. It it's still on version 1.0 with no updates whatsoever, or has had an update or two but hasn't been updated in months to be leery and stay away from them. Despite how many good quality apps that do exist on the store, I still stand by and refuse to purchase anything until it has a "+" next to the name. The iPad has been out for a few years now, there is no excuse whatsoever for what a developer cannot make an app universal to work on both the iPhone and the iPad. It's a bit sad to buy one, only to to find you are expected to purchase the same thing a second time for the other, often for a higher price for the "HD" iPad version.
Sorry for somewhat derailing the convo, I do greatly appreciate the post about a official program from MS that could easily help some people quite a bit.
