It is not a big issue for the yobit signature campaign, I think this problem occur because two days ago their website went down and there were no any response from the yobit community, and a lot of people thought that yobit gone (I think it is because the yobit community were offline and they did not know that a problem occurred in their server)
After that when yobit came online there were still some errors and people started to withdraw their coins, I think now their budget for the campaign is dried, whenever they get enough balance they will reopen the button.

could you, perhaps, just once, before posting here about something that insignificant, READ THE THREAD!!!!!  it needs to be stickied to the noobs forheads, because apparently they just do not have the time to read through a few pages and see that what they have just posted was specifically covered by the sig man and everyone was told to STOP POSTING ABOUT IT!

Payouts are not working corectly. ive opened a support ticket to get in contact with an admin.
Someg uys of you have the same Problems? Would be great to know

this is because of your post quality or you removed the signature first. I was in this campaign and I got removed from moderator when I join another campaign. I think moderator should remove everyone who left the campaign but the slot for him to joining again should be available, now I can't join this campaign and I feel it is unfair for me.

This happens barely once per month or so, i experienced it in the past many times and generally they enable the button again in less than 1 week
Avoid contacting them about it in chat, i remember someone getting banned by a mod for talking (or spamming) about this issue in the chat box

Now the problem is fixed, I can send the signature campaign earning to my balance. hehe. thank you yobit

They seem to have updated my posts, which is a good thing.

Maybe yobit system was under repair, why not try it again another time. Because just yesterday  yobit maintenence maybe bug still unresolved. Come back later dude. Thank you

Its normal ,it will be fixed soon. Just check it from time to time for to join on this campaign
