Yeah I think the different sites are
- palnet is minnowsupport.org,
- creative coin is creativecoin.xyz,
- neox I'm not 100% but check their profile out. It might be neoxian.org or cityofnexion.org or something like that
These all have their own token you can earn by posting from their front end or using #palnet #creativecoin or #neoxian tags in your post.
BRO you can only buy on Hive engine and can't earn it through posting like the others. But it also has a Discord/community and you can be curated by them using #mancave or #menofhive tags I think.
Hope that helps
It does :)
Cheers!
