Have to be honest with you, that is how all yhe instances started including lemmy.world.
but now they have enough reputation & users to make them feel like the safest option
There is no metric by which to know this yet as lemmy is new. Its not like there are 5 servers that are 10 years old and al the rest are just starting up. Just how it is.
compared with random instances with 2-3 users or so, a instance who is there since the beginning / relative long compared to other is safer feeling tho.
i’m so worried about this topic, that i even think about maybe setting up my own instance just to keep my accounts etc safe & from vanishing.
I feel like you have missed the points im my previous comments but if you just want to feel safer because in your heart of hearts this instance or that instance just feels safer then go for it.
My advice does not change. Make a backup account on another instance to avoid being burned. If you dont want to, then its now on you.
