And I thought me (almost) reaching my quota every month was making me a heavy user of the internet. I came across this on a torrent site:

Yes, that’s what it says. He’s downloaded 730 Terabytes, and uploaded 18,000 Terabytes. In about 18 months. That’s uploading about 1,000 TB/month.
Or another way, about 33TB uploaded every day. Which cannot possibly be right. 3TB per hour. 1TB every 20 minutes. 50GB per minute. Just under 1GB every second.
I put it that this is false.
And according to Wikipedia:
Which means he is claiming to have provided about 5% of Internet traffic over the past 18 months.
Even more strongly, I call his bluff.

No bluff needs to be called - they can upload that much, most likely using hacked servers or large pipes from datacenters.
Remember, this is a sysop/active warez group member you’ve highlighted, not a lowly home user.
