I have tested the sig myself the past couple days and i'm not getting any issues with posts being counted or not counted.
I'm still on my first week with the campaign but I have a feeling the "bot" counts everything based on the first registered post count
[not sure since I didn't check to see if my post count was 3569 "prior to this post" but my last post was around 6 hrs ago and based on bot counter, it's missing one].
from what I've learn from the Past Yobit campaign is that the Bot is Counting from the post counts and not in previous posts,so if your old post got deleted or the thread that you have posted then that will affect the counting of bot every 4 hours,so better check your final post counts before stopping to get a max post of 5 per day.
Update:Confirmed.
