Well, it was Christmas and the campaign lets people go away for 1 month (unless something like this happens). Its not like everybody treats this as their job and live out with if (imagine dinning with out family and excusing them to check Yobits bitcointalk campaign, lol).
I object to your thoughts. Take a look at the quote below. How long is your Christmas? You have at least 2 days to update the news and correct your signature, it's not too difficult for you to spend 15 minutes a day checking for updates from the work you're doing unless you don't want. It has been 4 days since the signature was updated and you don't have any time to check out the campaign you're doing 
I don't mean to accuse anyone, but obviously you can do better if you want, just 15 minutes is enough for all.How many days did you not post? Or how many days did you not put the correct sig? I had the cryptotalk sig for 2 days before adding the new sig and my account was not disabled.
I exactly do this after 2 days around 25 or 26 and change the code to the latest signature code but still, it ends up disable to inactivity which I don't know what exactly the reason why my account turn to disable to inactivity even I change my signature last 26.
Well, I think the problem is in their auto-detection or a bot with less time frame before they disable the account without giving other people a chance about their campaign.
Anyway, I think it's better for us to don't argue here because right now I decided to remove the signature code and I believe there is no way to remove the "disable for inactivity" for now unless admin will reset and let the other users join again.
