Those "abandoned" websites has nothing to do with Griffith or ECC team.
Actually, if you see well, that's the same template on all websites, but only the first one seems an old attempt of someone to make an ECC website. (Or just get visitors to the website it is redirecting: binarywatchdog.org)

Domain was registered 254 Days ago (as per registration info. Identity is hide, however), so it was in June last year, during that peak we had.

So, not much more to say about it.

https://ecc.network is the official website.
