An anonymous reader writes: Hacker, BVM, said he's "lost count" of the number of subreddits he's stolen and defaced, but estimates that the number is more than 70. Subreddits like r/pics, r/starwars, and r/gameofthrones, and many others, have been defaced just in the last few days. He claims Reddit's crummy security, and lack of two-factor authentication are what has made his exploits possible. "Reddit's security is shit," he says. "If Reddit would simply add 2FA it would be a lot harder to get in." Why is BVM hacking these subreddits? "No reason really. Just boredom. It's not like it's really a challenge or anything so I just do it to pass time," the hacker told Motherboard in an online chat. BVM didn't comment on how exactly he is taking over subreddits. However, he did admit he's been hacking into moderators' accounts and then changing the CSS style of the pages, replacing it with a note taking responsibility. Reddit appears to be responding to these incidents quickly, restoring the subreddits.
