why do you feel that your signature is worth any more than other peoples? i can see someone like tomatocage or theymos or other super highly respected members asking better money for their sigs but just normal members whom i see making these threads lately need to wake up. sorry no offense man but youre sig is worth what everyone elses is. find a campaign n make the best of it is my opinion.
it might be that rather than advertising some casino or exchange, he might want to give others a chance; example of this being izanagi's couple ring avatar campaign. there might be others that want to advertise the small services they provide on the forum for a small amount (graphic designers/artists, programmers, etc).
