I want to point your attention to one particular thin, which is called signature campaign You are already a full member,
It doesn't seem like the guy doesn't know what a signature is, perhaps he's already wearing one.
Op is not wearing a paid signature. There are so many bounty hunters who doesn't care about the regular bitcoin paid signature and who doesn't know how it works. If OP improves his post quality and enters a nice signature campaign, he will in no distant time rank up to Sr member because his activity count is big already. An average Sr member can earn upto $50 per week.
