Affiliate Marketing Secrets

We were living in employer housing and had our router (protected with the password it came with)connected to their internet. One day we were fired for-
1. using 80gb of data a month.
2. their system blocked 2000 attempts at accessing porn in 19 days.
I am 100% convinced that it was not us. It happened on days and times when we were working and or the computer was off.
I don’t know how this could of happened, btw- I am the husband…I think I would know if I was blocked from accessing porn 2000 times. I think I would have stopped after a couple of times of being blocked.
The employers IT person said that the only possible explanation was that we were doing it. I know we weren’t so what other possibilities are there? I don’t really doubt their figures, I just know that the conclusion they came to is wrong! HELP!!!!
