What to do about @TheGoddess?

[Lucifer]

@TheGoddess has made a fake account @GayBoy they have the same ip addresses.

She used this account to upvote herself like a 100 times, but worse she downvoted @sup , @football_m29 , @willoww and everyone who has more reputation than her atleast 30 to 40 times.

I think when her application to become a mod was rejected she wanted to get 1000 reputation quickly and wanted to stop others from getting that 1000 mark.

I have banned her fake account but she has to be warned at the least.

What should we do about her?
