Blackcoin.org is a website domain owned by a person.
A person I like and a co-founder of BLK, and the centerpiece of "community identity", but it's something which is "fully owned by a single individual" and thus can not be representative of "Blackcoin (BLK)" the chain.
BlackcoinOrg related social media accounts (facebook and twitter) are owned by other people (none of them me) and permissions are highly restricted and passed around within a social group which centered on bitcointalk, reddit, irc, gitter, and telegram - and slowly adding keybase - all owned by different people...
Most people deep into Blackcoin are so because we are decentralization fanatics.
TDLR; You can not rep "Blackcoin.Org" without Josh's permission - and best first you convince me or some other trusted person that you are not a scammer and we can talk to Josh together. We are happy for you to do Banners which do not include "Blackcoin.Org".
I've made a nice looking blog site for MVK's blog. :)
If anyone wants to contribute - we need intro and advanced tutorials.
This exchange now has BLK and BLN.
