If this site was deleted, I would be really sad. This site brings back memories. I’ve really enjoyed being a member here these past seven years and even though this site has drastically decreased in activity, it is still to me. I come here because I enjoy this site and the people here.
Creating a false announcement definitely is not the way to go, though. Forums are dying in general. This is a wonderful community, but it will never be like it used to be. Activity may pick up once Animal Crossing Switch is released, but not too much. That is just the reality of Internet forums. It is not just Animal Crossing Community; it is all Internet forums. Social media is taking over.
If I had my own world
I’d build you an empire
from here to the farlands
to spread love like violence
The hope is that they get nostalgic and decide to stay rather than be irritated by the deceit. Jader'd have to post an announcement when "closing date" arrives saying that due to popular demand he's decided to keep ACC around after all.
