@psylancer If you got 100 million users so that it's costing 400 million dollars a year, then ideally you need one million servers with 100 users on each. They need to all pass around a hat between their 100 users to raise the 50 dollars in server costs a month.

Each instance funds itself. Some might try ads, but as of now, most are just funded by donations.

I think the price is spread out across multiple generous people that generously host instances. I think it really depends on how much members there are. From what I heard my instance is 25 $ a month. Another instance I was in on Mastodon cost a few hundreds bucks to run. This is why it is good to help out your fellow admins. On the other hand, lemmy and other fediverse software are open source, so they don't really have to pay for developpers. Also the scope of what lemmy or Mastodon do is considerably smaller that Facebook, Twitter and the likes. Facebook isn't just a social media, it's a spying engine and an ad recommendation platform, Lemmy and mastodon are just social medias, so of course it costs less to do.

Personally I plan on donating the price of Reddit Premium to my instance owner

I'm running a barebones server for myself and a few communities (not many subs yet) which will run for less than a Starbucks coffee a month... (Assuming I don't need more storage space... Lemmy seems pretty light. The main servers are gonna carry the load unfortunately... Beehaw.org had a transparency post about financials as of about a week ago they said something that their instance was costing like 50-75ish a month of I recall.

donations to my favorite instances, like wikipedia i hope :)

Given that lemmy is an OSS project and decentralized, it draws a lot of people with knowledge and resources. You could easily host your own instance for your friends, to have them connect to other instances. And i think there are enough people in these communities that have some left over server resources to host their own instances.

There already is a question similar to this. You can find lots of ideas there :)

Are ads forbidden?

The thing is, Lemmy is decentralized. You don't need to have an account on an instance (server) to use that instance's "subreddits" (communities) - instances communicate their activity to each other automatically, so any instance will do (provided the instances haven't banned each other). It's just like email.

So it's pretty simple to just stop accepting sign-ups once an instance starts to become impractically large. Anyone can start an instance for just the cost of a domain ($10ish/year, or free if it's a subdomain of an existing website) and a server (that random computer you already have lying around will do just fine, for free). And a small instance can do fine on just donations and the good will of the operator.
