An alert from PrimeGrid's forum:
The domain has been stolen by a cybersquatter. The real website is being rebuilt at The squatter is using some content from the old website to make the new, fake website look "real". This is clearly an act of deception. It's unclear whether the squatter merely wants to use the site as clickbait for ads or wants to do something more nefarious such as distributing maleware. Either way, please avoid the old website, and please pass this information along to others in the prime search community. Thank you!
