I made a couple. Lemmy.ca which i call home, Lemmy.world, for anything american, lemmy.nsfw for... stuff

sure i could do that all from a single instance, but why not diversify

A good use case is limiting who else can take your username. You realistically can't create an account on every single instance though. Instances come and go.

If you plan on moderating communities, it is useful to have an account on the same server as the community you are moderating.

If you plan on just browsing, posting, and commenting, you don't really need multiple accounts. Some people prefer to have a separate account for NSFW stuff, others don't.

Yes. You can continue browsing Lemmy even if lemmy.ca or even one of the big servers has an outage.

Alright, thanks for the help y'all. Guess i'll make 2 or 3.

If you do make multiple accounts, note that you can also copy settings between them such as the subscribed and blocked lists

1. Go to your user settings
2. Export the data
3. Import it into the new account

Note that it will also copy over other settings unless you manually modify the file, so keep that in mind when importing
