It was a disaster in the 90s (which is the last time I used it). I can't imagine it got any better. It's probably 100% filled with CP and other porn now. I wouldn't touch alt.binaries with @boone's dick. What are you expecting to find on Usenet?

Just curious as to what state it's in these days. I would just assume it's contaminated.
