Yes, and oh boy, did I feel bad about it.
I was analyzing traffic on our network when I saw the URL and IP for the board flash across the screen; when I checked, I saw that the local IP accessing the board wasn’t my computer’s address, so that must have meant a co-worker also read/posted to the SDMB. After tracing the local IP back to the computer using it, I noted the company user to which it belonged and filed the info away in case I ever met up with her. I figured it’d be a fun conversation to have.
What I didn’t count on was my own bumbling of the situation. The next time I saw her, I took her aside and asked whether she posted on the Straight Dope.
“No!” she said, almost frightened. “I have so much work to do that I don’t have time for personal browsing.”
I was confused. I knew the traffic came from her computer, but here she was saying otherwise. Plus, hey, stilted and formal speech. It took me a few seconds, but then I realized that, in her eyes, a company system admin was accusing her of wasting company time.
“Wait, I post there, too,” I quickly told her. (She was about ready to bolt.) “I just happened to see traffic going to the Straight Dope and thought I’d say ‘Hello’ to another user. I don’t care what sites you visit.”
After that, she relaxed a bit, and we talked for a few minutes, but I could see that she was still pretty uncomfortable. Alas, I may have scared off a potential paying member; thus far, she has let her guesthood expire. I guess I oughta throw in $15 to make up for it.
