According to Lachan Feeney, the CEO of Labrys- an agency that deals in blockchain development- close to 45% of the blocks of ETH are being validated. And these validated blocks operation of the MEV-boost relay flashbots, while complying with the sanctions of the United States.
In an interview with Cointelegraph on the 30th of September, Feeney went on to note that while there have been reports stating that close to 25% of all blocks that have been validated have complied with the sanctions imposed by the US government, there is still a major lag. The closer number could most likely be one out of every couple of blocks.

Feeney also highlighted that the ETH relays employing MEV-boost were mostly about regulating the businesses- sometimes based in the United States, and therefore censor certain transactions in the same block that they create- especially if it belongs to transactions made from Tornado Cash.
Feeney also mentioned that the validators used the MEV-boost relays because they had a financial incentive to do so. For, using this algorithm would create an increase in their usage. The CEO mentions that the main issue that would come from the perspective of the validators would be that there are guys who are paying them to create this.
The above studies have been reinforced by the research conducted by ETH researcher Toni Wahrstatter, who went on to publish this research on the 28th of September. He further suggested that none of the blocks that were verified by this Mev-Boost relay had any transaction done from Tornado Cash.
