You just answered your own question. What's wrong here?
Where I participated with both accounts? If I joined Ariva Twitter campaign with both accounts then you can call me cheater.
With 'Rana590' I joined signature and If I wanted then it was possible to join Twitter campaign also with 'Rana590'. I didn't use it on Twitter campaign because I didn't want to participate in social media campaign this this account.
I used separate account in separate campaign. That's indicate no intention to get double payment. My intention is solid.
