Yes, the sentence is grammatically correct. It conveys a request for someone to refrain from engaging in sexual relationships with their neighbor, even though the speaker is unclear about the intended audience of the message. Here are a few possible rephrasings: 1. "I'm not sure who this message is intended for, but please refrain from having sexual relationships with your neighbor. Thank you." 2. "I don’t know who will read this, but I kindly ask that you avoid sexual relationships with your neighbor. Thank you." 3. "Although I’m not sure who this applies to, please steer clear of sexual relationships with your neighbor. Thank you." These alternatives maintain the original meaning while varying the phrasing.
