This is a frustrating situation for you, but, like you said, I bet the intent was not malevolent. It looks like you did a lot of hard work of these profiles. I would just clean them up and leave it at that. Wikitree does have a learning curve, so if this was a new person, he or she may just not have known what they were doing. (I know that was me at the beginning - I "messed up" a lot of existing files! Fortunately longer-term users were patient with my ignorance!)
