I just checked my account and it looks like my payout address has been changed and locked (it's now 6xEjXTc9cSJzDatsBD63Z1WnT8GjLKP8au which is not mine).
I can't work out how to contact Digger, the site admin, because there is no email address for him and I can't send private messages on the board yet. If anyone can assist then that would be great.
It's a little disappointing. I think I had just got enough coins for the payout to work and then this happened.
Same here. Locked yesterday my address and today was changed. Also it become unlocked. This happened between 12-13:30 CET. Unfortunately I put back my address so I can't say 100% sure it was the same as yours but I kind of remember was ending with 8au.
