So last week I was able to bypass facebook's mobile verification for one of my accounts using k7.net. Today I got another roadblock so I decided to use k7 again. Only this time, I'm still able to receive a voicemail file but the file is only 1.5k and 2 seconds long which means that there is no voice. Does this mean k7 doesn't work anymore? I've never tried pinger before so I don't know how to tell if it's not working anymore.
