It doesn’t look like the domain name lapsed and got picked up by someone else, but it could soon. The expiration is July 17th. If you dig down to other URLs on the site, there’s an old install of phpBB there with the usual forumosa skin on it. Older versions of phpBB have known security bugs, so it is quite possible someone exploited one and hacked the system.
I’ve got segue as one of my “favorites” and in the past couple of days every time I click on it I get that same hacked message. By typing in www.forumosa.com I don’t have a problem. I wonder what was their motive. Lately I’ve been getting pop-up garbage every time I start up – is it possible their hacking resulted in those pop-ups, which I then click on to remove, possibly generating income for them?
