Alright, thank you anyway.
I've found a solution for my problem. Using walletnotify, when a transaction hits up, I'll log it at 1 confirmation and make sure that the category is "receive" and the account label as well. This should be a fix for my problems. I could first check for confirmations, category (whether sent/receive) and then finally the account label itself.
Very cool way to Spam the forum. Clever. Good luck with your new product.
