Regarding the latest attention to WOT hacks, due to the massive amount of youtube videos.
The most comon videos seen on youtube, are fake videos. They are not hacks but keyloggers.
This is also what is said in the official WOT forum.
They claim that there are no hacks for WOT. But it is a online free game.. so... of course there is!!!
They are not that easy to come around though, so hackers in WOT is not yet a everyday happening.
