Internet limit

My family's internet is depleted in have a month for 5 months now. I watch a lot of anime. If we have 70GB of internet how much anime episodes (20mins) will deplete it. I think it might be that someone is using our internet.Edit: my service provider is rogers if that helps.

there isn't enough information to answer the question. the resolution and bitrate are also very relevant.That said, streaming video/audio will deplete a monthly transfer allowance MUCH faster than you expect. Bittorrent/P2P applications are also a likely culprit.
