You can use your signature to fill it with someone signature and you get paid for do that. It called signature campaign, go to service section and you will find many signcamp and the rates are depend on your rank
he wasn't asked how to join in signature campaign or what's that definition. Re-read carefully what he asked.
Tell me if you got solution for that.
the only solution in my mind just joining in signature campaign which makes daily payment (like yobit) But unfortunatelly yobit campaign currently already full, and you can't join because the lowest rank they accept is Member rank.
