Yeah, I don't see why it's so difficult to hold back things that could catch up to you later. I think everybody has to (or should) use a certain amount of discretion when posting on the internet. You can contribute plenty here without mentioning outside friendships. If I recall correctly, some time you ago you made a similar post regarding this. Unless there are people who know you post here, it seems unlikely that anything would come of the info you've shared on the forum. However, if you're still worried about your identity being linked to anything here you could ask for your interview thread to be removed and username changed to something you don't use elsewhere. That may not be ideal, but it would be a bummer to see you go!
