When I count my posts since last Saturday 12:01 AM, I count 12 posts: https://bitcointalk.org/index.php?action=profile;u=527271;sa=showPosts
But the count wasn't done from Saturday 12 AM UTC.

I think there was very short notice as to ending the signature campaign. I expected a message to come out, but since it's now Thursday I would have thought this full week might still count (posts till Saturday) or the whole week would be disregarded completely, because the ICO finished this week.

Now if I had read this notice 4 hours ago I still could have made a few extra posts to finish off this week, just like I'm sure others have done. Now for not reading the notice in time I won't get any stakes at all for this week (only needed 3 posts according to count).
