The site is manually moderated. I made the mistake of posting it over my lunch break and had to go back to work which caused a significant delay. I'm back on processing things now.
Thanks for moderating it, I figured it was too good to be true that none were horrifying/"ear rape" without manual moderation. Out of complete curiosity, what type of things are you finding the need to filter out/remove the most?
Not too much, actually. People hanging up without a message are the most common. There are also a few people that have played recordings of songs or other sound clips from copyrighted sources, and I don't want to deal with that mess if I don't have to. There are also the ones that are in other languages that I can't put a good memo on or moderate properly. I keep them all and just leave the ones that I don't post marked as "unpublished" in my static site builder (Jekyll) so that I can take another pass at them later when I have the time / resources.
Very few have been "inappropriate". There was one with some questionable jokes that I held back and another where someone was quite angrily talking about a particular political party (there are other "political" statements I've allowed; I just don't want to the page to become some place for people to yell at each other -- not going for that vibe).
@unixispower , you might consider adding the site to TheOldNet webring ( https://webring.theoldnet.com/submit ). I have discovered it from a yesterday post about ucanet (a DNS for retro site). Your site would be an excellent ring member!
