one can come,stay for 3-4 days make the posts and he is eligible for a reward and i am not? hmm..can i come back in the last day?then, i would not brake any rules...i would actually wear the sig at the end of the campaign. i hope we are reasonable about this
No.
You should read the rules. There are no signature campaign that allow the user to stop in the middle of campaign.
(When you change your signature, every post that you make before this will show your latest signature, so tell me what is the benefit of the old signature project gain from this?)
I gonna give you 24h from now to wear it back or I will disqualify you from the bounty program.
