I've been active for like the last year or two, and its been mostly just me.
Occasionally I think old devs peek in, but there ain't much news or updates, or even active players. Just lurkers and newbs remain...
I reckon I'm as close to a mod or dev as you'll get and I'm completely unofficial.
The community has moved on to newer games.
I keep my server up mainly for nostalgia, I did my best to get it back to how I had it configured circa 06-08. I more or less taught myself how to code games those summers, using this platform. Even when me and another friend are actively playing, we never seem to get any random pubs...I don't think I've ever had more than four simultaneous players since I rebooted in 2014.
I was huge fan of the Jiggly Fun House SourceCraft TF2, and scored a copy of the source code their lead developer Narus ended up sharing...this is just as dead as cs.16 superheroes tho.
There is interest in porting the game mode to CS:GO
Here is a [REQ] page up for it...
