I could have been the person that sent that email (but I wasn't). In college getting my CS degree in the mid-90s, I had a job as the sole sysadmin at a small in-town ISP at a company that had the ISP as a side-business of its main business which was embedded systems development.
The ISP consisted of two PCs running Slackware, a Livingston Portmaster, two dozen Hayes 56K modems and a single T1.
I would have been the person reviewing access logs each morning and would have noticed someone connected for 20 hours that hadn't been sending any traffic.
Yet, I don't recall every having to send such an email. We _may_ have auto-disconnected sessions after a period of time to let other callers connect, but I don't recall.
