What I only see there is a retweet and it should not be used as a proof for alt accounts. But if you say so, then the owners of those other retweets will be marked as alt of this user as well?
Both of the users used the same twitter handle. Have you got the point? @NinBarongo twitter account was posted by the OP's banned account, Goethe a banned user also posted the same twitter account a while back.
