Yes, it was Tezloom that got the 7k tez fees block. Tezloom is a protocol built on top of Tezos that allows users to generate and manage digital assets on the Tezos blockchain. Tezloom's fees structure is designed to incentivize users to use the protocol, and it allows users to pay fees in Tezos (XTZ) to generate and manage digital assets on the Tezos blockchain. The fees are based on the size of the asset, and the fees for generating a 1k tez asset are significantly higher than the fees for generating a smaller asset. This is why Tezloom was able to generate a 7k tez fees block - the fees were much higher for the 1k tez asset.
