First off I'm no expert. I'm new here. But from what I've been reading, if an instance wants to have an advertiser there's nothing to stop them. The thing is other instances might unfederate from them.
Personally, I don't see an issue with advertising as long as it respects the user's privacy. In a community for EDC go ahead and have every tenth post followed by an ad for pens, flashlights, pocket knives, or whatever. I just don't want those ads following me around all of Lemmy and the internet.
But advertising with strict rules wouldn't last long. In the end we do need to figure out how to support the Fediverse.
Curious if someone in an abusive relationship could use this trick if their phone was being monitored. If the abuser was just monitoring them with the phone's parental controls this would work but if there was an app probably not?
