I am not unresponsive, I only reply to those who gets selected in the campaign. Since there is still a spot open for Hero/Legendary, I occasionally check all the users who apply for that spot but still haven't find one with good post quality.
It's not up to me whether there is an asterisk or not but maybe just posting something like "all outstanding applications denied" occasionally would reassure people that they have been looked at.
Paractor's campaign has a red asterisk because he was unresponsive around June or July (not really sure, back read to find out). Since then, I was watching the campaign for the manager's updates regarding the applications, there are none so I thought he was still unresponsive. A reply to the applicants would be totally awesome so that they know that you've seen their accounts and they weren't qualified instead of just waiting for nothing. Now that this is cleared out although I strongly suggest doing what TheQuin said, we shall remove YoloDice's red asterisk.
