Possible Security breaches???

anybody ever heard of this site?

it allows ITS users to login a website using other folks username and password. they dont even have to register.... they can use somebody else name.

im pretty sure its nothing at all...just thought i should let yall know....

with the most basic know how of hack it takes about 3 minutes to be able to go to any forum and grab a user name and pass so you can get in and post under thier account or change thier posts.Id tell you where to even see a step bt step video but I probablly shouldnt share that with everyone as who knows who will use it for evil lol
