Is it the bitcoin foundation?
No. The Bitcoin Foundation has nothing to do with the forum.
Both bitcoin.org and bitcointalk.org are owned by me and theymos, though I'm more active on the bitcoin.org project, and theymos is more active here.
Satoshi and Sirius used to be involved, but they're not active anymore.
Since you and theymos own bitcointalk.org, why is it that your account only ranks as a Jr member instead of an administrator for example?
Or is it due to the fact that you only focus on bitcoin.org as you are more active there as you said?
Well I don't know about cobra, maybe I am hearing for the first time today but from his profile it seems that the account has been registered in 2014.
Below the nickname is clearly stated the Custom Title: "Bitcoin.org domain administrator"
