Definitely yes, how ironic that until now there's a lot of participants are creating of illogical question! We all knows or else most of the participants in this site were join in signature campaign because they paid by the ICO promoters. So there's no reasons to asked it again in again, because it is results of redundancy to the topic.
I was wondering , do they really help to promote ICO , i know they spend a lot of money to pay bitcointalk members to wear their singatures and make posts . Do they really make profit out of this ?
Wearing signature of one participants not means that they can earn income immediately, try to review first the signature campaign you join if you accepted? Other than that review the rules and regulation of the campaign you join if you meets it and review when the campaign ended to see if they already finished or not.
