I've noticed some people have alot of problems on nostr. I've been ok so far, sometimes takes time to update refresh. I've only been here 4 or 5 months. Possibly because I don't actively create my own notes, just reply to other peoples notes maybe that's why my experience is different. Plus I don't have lots of followers / follows, so maybe I'm passing under the radar because of this and not targeted.
Tbh I don't completely understand how the whole relay system works/ decentralised etc.
I discovered DM aren't always private either.
I'm just relieved I can express my views without being censored. Generally when people don't like my opinion I notice they just don't respond or engage as much, rather than getting into a full blown argument like fb / x. Ironic, but more freedom feels like result is more respectful. When you'd think it be the opposite.
