In the screenshot preditor422 is wearing the signature for yahoo's signature, but nikjain422 is not. It would be understandable to have sent this on the wrong account, but I don't understand why/how you managed to send it on both accounts; that seems a bit odd to me. I would suggest you tread more carefully in the future and redemption will surely be possible in due time.
In nikjain422's post history I can't find anything about that campaign, and I don't see either of these accounts on the spreadsheets from the Eroiy campaign. I haven't gotten a chance to see if they both applied for the campaign, though. If it is true that both accounts were not enrolled nor applied, then that would seem excessive. Also, a single merit sent between alts is not something I would personally constitute as abuse; I can understand standing on principal, rather than on the quantity though, if that is the argument.
