Sounds like some thieve(s) tried to use already promoting profiles to submit their own wallet to basically steal some of the bounty payouts? Shouldn't that be easy to handle? In case of such "intentionally submitted multiple entries" the profile owner should be contacted to verify the wallet ID. Then filter out the submissions that don't match.
And you may be right sir. Since mother of idiots is always pregnant, there may have been some idiots trying to steal "profiles" to fill in their pockets without doing anything. Me, for example, I've submitted the form only once, if there's more than one, the new entries are not mine. (but I've always been paid so I don't need to be looked into it either)
