Do you guys think our emails on Yahoo mail are safe after this? I will backup mine as soon as I find the time to do so. Yahoo has a terrible track record regarding emails. I already lost one due to inactivity. They gave it to somebody else. That somebody probably has access to several of my accounts now. On websites where I used my Yahoo address and then just forgot about it.
