Same issue, had a bunch of coin in there. If the owner of the site is on here and reading this, please PM me
I tried and got this error:
User 'blender' has not chosen to allow messages from newbies. You should post in their relevant thread to remind them to enable this setting.If he isn't checking this thread, I would appreciate someone capable drawing his attention back here

admin or moderator can help somehow that we get in touch with blender ? we had there customers funds on accounts !
I'm not sure if they would put the website back again a third time. But I'll PM him again in case he still hasn't wiped everything he had on BitBlender.
i still see here a lot of discussion but not one which could help us recover our funds ! admin or moderator or old member in here maybe can help us get in touch with blender ?
