Plausible . I'll tag them with a message to reply here if they want to clear their name

Just wow.One of the following addresses belong's to  bikoBoy who is a known scammer with multiple alt's.I think all the accounts he has purchased from you should be negative repped right away.

Proof :

You,said that you have previously dealt with this person. Do you still have the btc address where he sent the payment from on your previous transaction? Also it will help if you could mention the skype ID, email or the username of that person tha he uses on dealing with you. I'm pretty sure that guy can be tracked if you can provide the details.
Think this as a lesson ad always have a signed message on your account. We can't tolerate a scammer like this so please be more carefull.

Who was the original buyer of the accounts ? Could you please mention his UID as well?

Signature campaign would be the best. But yeah, Newbies can't have good styling on their signature and hence the low payouts. You need to learn more about Bitcoin while contributing to the forum for now till you get to Full Member and you can then earn some pocket change.

Other than that, I would go for currency exchanging or services. Currency exchange requires huge sum of money and a fair bit of risk if you're doing reversible method to Bitcoin. You can offer your designing or coding skills by creating a service in the service section as well.

If you live in a country that has unique goods and it has high demands, go for selling goods at the goods section. It would yield some profit depending on your fees. Use escrow to let people trust you though.

There are different ways:

1) Participate on a signature campaign and earn Bitcoin for posting
2) Use your skills - programming, videographing, texting...etc - to get jobs on the Services section
3) Do community work for various altcoin projects and exchange the alts into Bitcoin
4) Use faucets and / or register for Bitcoin for click sites like coinad.com or btcclicks.com
