This may look like a weird question btw.

I see constantly people here worried about digital security, I see people using Tor, deleting social networks, and just sharing the different levels of security that they use.

So I was wondering, how safe is Lemmy? Sure it doesnt collect info like Twitter and Meta does, but that doesnt mean its 100% safe. So what are the main problems we can have here? Is there anything the 3 letter agencies could exploit? Is there any preventive measures users could take?
