Anything you post on the internet you should treat as public and permanent. Before you post, ask yourself “could this come back to bite me?” If the answer is yes, It’s probably not wise to post it to a public forum. I do believe that organizations, businesses, and various aspects of the government monitor online activity. You would be wise to limit what ”wrong-think” you decide to post.
Can I buy it off you? I have one that I’ve been using for years and it’s slowly falling apart.
