theymos never struck me as someone willing to shot himself in the foot. He knows very well the traffic that is generated from signature campaigns as well as the altcoin boards. That's why there is no such option in the poll 
It's true that chances of signature campaigns getting removed is very low, but that could still happen, meaning it should have been included in the poll, imho. Even more so as we know that big part of the forum activity is the product of the ongoing signature campaigns so it would be interesting to see how many would vote for that option. I voted for several "Age, family, life, and/or personal problems prevent me from being active." since it was the closest one to the reason that could get me away from the forum, and its simple boredom. There are forums that I am active for at least ~20 years, and every 4-5 I got fed up and take a break so I guess it could be the main reason for leaving this forum too (at least for some time).
