> Can anyone explain what happened in this block of transactions to me?
These transactions were sent from a vanity address(es) [1], and in this case they're used to spam the recipient with implied messages, specifically about their poorly viewed scam--take it as a 'l33t' way of sending a message, hence the amount on the last tx. Another notable one was the EnjoySochi, as in the Olympics, transactions that spammed the network for a while 6 years ago [2].
