From a business perspective, each team will consider to hold the campaign in the near future if many users are willing to use the signature for free whenever the campaign is paused. Hhampuz has informed all participant at the end of each week period when the campaign is paused that "you are free to delete the signature from now." So consider not using the signature when the campaign is paused as this will trigger the campaign to resume as soon as possible.

However, every applicant will get the same opportunity every time the campaign reopened if you have the qualification according to the campaign's needs. So it doesn't matter if you are using or not using the free signature at this time. Sorry, this is just my understanding.
