It's understandable. Maintaining a website is a lot more work than most people realize, especially if you're the owner and you're seeing the activity dwindle to nothing.
I was an active poster at GolfRewound for several years, checked in every couple of days or so. Not a lot of people there, maybe 15-20 active posters. But they were good people and we felt like we knew each other well enough to stay somewhat active and remain connected.
Then one morning several months ago I clicked the bookmark to check in and see what was going on, like I normally did every couple of days or so. Nothing, it was suddenly a dead link. I guess the two guys who were running the place decided it was no longer worth the time and effort, and figured that closing the site unannounced would be the most practical thing to do. They were probably not wanting to deal with the obvious pressure from the remaining active members pleading with them to maintain the website. It was a shocker though, like coming home from work and finding your shit out in the yard and a "not welcome" sign posted on the front door.
At least they saw fit to give advanced notice at FGI.
