Criticise what I'm suggesting, but first understand my position. Ask questions. Don't assume.
You thought about security only after found several strange 1 NXT incoming transactions. Fear made you to move and speak with community.
Would you like to fund fully completed bounties, which may be interested to you?
Just create a new bounty then, it can be for example - "Security Research of NXT account in forging status", which 'll lead some real specialist to make some really complicated analysis for you and community.
Fund and develop bounties you need, or create a bounty to look and manage good bounties for you.
