I saw that he was online a few times and didn't post anything, so he clearly had access to his account and to the Internet. It takes less than 10 seconds to write "I'm terribly sorry for the delay, I got some issues, will explain on the (date)", especially when you're already logged in, like he was. He didn't do it = he doesn't care.
You missed previous post on this thread where Lutpin message was quoted. I'll just quote it again for you:
I'm preparing payments to make up for the missed rounds.
They'll be sent out tomorrow morning.
After that, the campaign will switch from bi-weekly payments to monthly rounds,
but more about that once the payments have been made.
I'll also talk to bitblender about whether, and if how, to transfer the campaign.
And you missed the point of my post and this thread.
I was talking about the time before he came back. About those weeks when he was ignoring people and not paying them (before november 27) and he was logging in and not posting anything. I also didn't see anything close to "I'm sorry" in his post.
