Indeed. As I mentioned in another thread recently, I’ve found posts that I posted on Usenet from 17 years ago. All of these posts were under my real name. I even had a signature block with my name, e-mail address, department, and university, along with a clever quote.
At the time, most Usenet posters had their internet connections via universities, the government, or the corporate world. To post, you had to have an e-mail address, and most people’s e-mail addresses were based on their real name. For this reason, it was common in those days for most people to use their real name for their username.
I was certainly aware of this fact when I posted. Far from baring my soul, I did not post anything that had the potential of getting me in trouble with my university. In fact, at that time, you had to get special permission to be allowed to post onto Usenet. Posting privileges could be lost for “inappropriate” use.
It was not until several years later, around the mid-1990s, that commercial internet service providers became common and user-friendly enough to use that people generally had more anonymous e-mail addresses and usernames.
