Best punishment would have been to suspend a week's pay , just to let him and all other campaign members know what the consequences are for this..and probably some comments on the spreadsheet to alert everyone that you have an eagles eye on them.
The punishment would be determined by the campaign manager.
Two people Cro2 (Trofo and cryptofrka) are managing the campaign. Both of them have posted but you did not read their post. Cryptofrka posted that he will be removed from the campaign.
I am surprised that he has not come to post anything about it which makes the judgement accurate.
