As far as i know @Sinister Smile from this forum (not personal) he start learning coding like 1-2 years now if i'm not wrong.
He was doing good jobs and share it for free, and he was friendly to anyone.
Also i have seen his work on some private server and nobody had problem with him.
For this case i don't know what goes wrong with that deal, but i don't think he or somebody here with good reputation will scam your 10-20 euro.
In personal i think he is good man, and even cancel the second deal he sends you your moneys back.
Also for @tazerman2 i can't understand what wrong with him too.
A lot of my client's telling me that they have bought codes from him and they call him "L2DevLuna" and "Marios".
Also i see him in lot of topic to request help for really "newbie knowledge" request's.
