So this happened like 5 months ago, just posting here to find out if anyone else is getting such emails? Where to report such blackmailers? and how to deal with them? If you have any suggestions please post so it helps the people who get such emails in future. The site was ranking top 5 but was not generating much income so i never replied that guy and i never saw any backlinks blast ever done to that site so it didn't harm me. For me the best solution was to never reply them, but if the site was important to me i would have probably replied and even paid them.
