I've been trying it for concurrent to Rif and Sync. The differences are individually small, but taken as a whole the official app is just horrible. If it weren't for Rif and Sync, I don't think I would have become a Reddit user. I'm desperately hoping Lemmy reaches the critical mass and Sync for Lemmy becomes a thing.
Is the poster's IP address, system, or other system identifier/location, tracked?
If I have users giantshortfacedbear and throwaway123. Then it could be inferred or impled that they are same person if there are from the same IP or phone.
