Privacy invasion brings some laughs
Years back in a very large engineering firm. The IT dept demonstrated it's snooping power by emailing the entire UK workforce, over 1000 staff with a list of the top 10 most hit websites of the previous day.
6 of the 10 on the list were recruitment websites. To this day I have no idea who on earth thought this could be read as anything other than a clear message that it was time to jump ship. Oddly, another 2 sites in the top 10 were Barbie memorabilia.
