I don't believe anyone here was condoning child porn.

As for sending 5mb in 5 minutes...

How long has your client been connected?

Were you searching for files ( any type ) or just letting the program run?

You say you sent/recv'd this from 2 ips is that all you were connected to?

Where did you get the 5mb number from?

P.S. I am not trying to discount your problem just trying to help
answer it. And no I don't condone child porn either.
