Given the fediverse is a not for profit, any advertising campaigns would have to be fronted by someone who wants to pay for it. It’s not that we can’t do advertising campaigns, it’s just we can’t use the money people dontate to keep the servers running for marketing, because people expect that money to be used in making sure the server exists into the future - it would have to be a separate donation soley for marketing it, or maybe some rich person could decide to pay for marketing in full.

On top of that, we can’t let sign ups exceed to amount we get from donations - that would kill the server or force the server owner to shut down sign ups and, worst case if they happened way too fast- the owner remove some of the more recent signups, which would reflect badly on said owner.

In other words, if you want to advertise it, go ahead but don’t expect anyone else to contribute cash to help as marketing a open and donation based system like this could have its consequences.
