Like, post a ton for years on end as an active part of the community, and then just vanish never to seen again afterwards? Because I've had a few cases like that before. For example, on a previous gaming forum, I had someone who posted dozens of times a day, contributed every kind of content to the site and welcomed every new member just up and disappear at random a few years later. It's like their presence online just went completely dead at random, and no one's ever seen them since. And the same goes with people on a few other forums too. I've seen people who've been on a site for decades just stop visiting without saying anything, staff members stopping logging in for no reason whatsoever and all kinds of other examples of people just disappearing at random. So has that ever happened on your site? And if so, what do you think could cause an incredibly active forum user to disappear without a trace, or even seemingly stop using the internet at all?
