It happens all the time. It was really bad from 1 dude a few days ago Clients filter better than others
Which clients are you using?
iris
Give a shot to Coracle
I would love to use Coracle. But......the user experience for viewing the Global timeline is bad. If it kept the Global timeline flowing, I would self-host it again for poster.place. Nostrudel and Snort are the only Nostr clients (desktop) that seem to keep loading posts right. Primal has issues staying connected to relays and keeping the timelines flowing too.
Amethyst or Snort on desktop
Really strange, I muted some npubs months ago and never had other problems
