I would definitely block that and other certain categories. There is zero proof at this time that blocking categories or ad networks guarantees that your earnings will go down. In fact, my data tells me just the opposite. Being opted into the dating categories may have a TINY positive effect on your earnings in say the finance category. But what if all of a sudden you have ads related to dating and no one is clicking on them? Then your CTR tanks and you make less. In my experience with AdSense, common analytical and business sense trumps all the "rules" and "best practices" they want you to believe.
