This question already has an answer here:
Should I report a user for having three duplicate accounts? And if so, how should I go about this?
On all three accounts, which are all clearly variations of the same quite specific name, the user has been posting the gamut of answers, ranging from incorrect or low quality answers that could be improved by some research to thinly veiled rants about the site.
I down-voted and/or flagged many, as well as attempted to make some constructive comments on why they were inappropriate according to the site's guidelines or not sufficient for an answer.
I am not trying to be a serial down-voter, but many of this user's "answers" are just plain bad and harmful to the site.
I have noticed that some of the user's comments and answers have since been deleted, which may mean that the problem is being resolved by moderators. However, I'm still concerned.
Is there any way to contact a mod privately to disclose the user's usernames, so that they can look into it further?
