Just to add to this (I've been a long time surfer of the forums out of pure interest... Never posted before.)
@local: This isn't a COLO issue. There is an awful lot wrong with this forum and the larger server aus99_admin is using. I've emailed in before, though never received a response highlighting the plethora of issues with the webserver. But seeing the site admin active here, this may gain some traction.
Combine this with the general lack of support for SSL (Edge doesn't work. TOR/Brave seemingly does?), and this is a recipe for disaster to be blunt. Even with SSL support, the forum software is so old that hacking into one of the (sub-)components isn't likely difficult. vBulletin's software is a bit sh*t as well, with the default hashing algo being double MD5. Any password below 12 characters would be crackable in minutes, possibly hours. The only note-worthy thing was having a test device be IP-banned after the port scan.
*Just to add: I haven't actually attempted anything. I have no idea whether the DB found in the port scan belongs to this site.
TLDR: The forums is chalk-full of security vulnerabilites and needs to be patched today. However, without knowing anything about the admin's technical knowledge and evident lack of maintenance already, I'd surmise that won't happen.
