if you can only see "removed from campaign by moderator" at https://yobit.net/en/signature/ then you have to check this off and forget about it.
as you can see here i had the same problem... or i still have it. yahoo can't help that either. the people in charge of the campaign have no interest in the individual fate. it's best to look for alternatives and don't worry too much about it (even if it's not always that easy)
the other points have already been discussed in detail. just wanted to say a few words about the CT campaign.
