Wow.
Mediafire just implemented their new, "Download Threshold" system. This is what unregistered users will have to face if you download a certain number of files from Mediafire. You get this, "Download Threshold Exceeded" message, and I have to wait 44 minutes to download files again.
Good thing I have an account on Mediafire. After logging in, the message didn't appear no more, so I was able to download files as usual.
A bad move for Mediafire imo, but hey, they need cash too? And it seems like they are looking for new ways to make money.
P.S. Forgot to add. I am a free user and I don't pay monthly to use Mediafire, yet I was able to download right away after logging in. Weird, but oh well.
