I made a website for a guy, been keeping a casual eye on it and it's fine, if boring.

Then he calls in a panic to tell me it's been hacked, there is porn everywhere and funny underlined words and I must fix it right now!

So I drop what I'm doing and access the site and it's fine. I use a few different devices and even a couple of different networks and can't see a thing wrong with it.

Then I spent half an hour on the phone trying to convince him that his own shady surfing habits are causing this on his computer only.

I get the feeling he didn't believe me because he hasn't paid the latest invoice..
