@pv Hi. Vincent! Yes, I mean #Diaspora - https://joindiaspora.com which you can install (in there we call pods to stuff that here are instances), or use by joining an existing pod.
It was all the rage almost a decade ago, and it's starting to gain some track again, with new users now too, thanks to this whole #deletefacebook thing.
As for Portugal for allergies... Ah, Vincent, I'm afraid you're going to be stalked by them anyway. :x
