Is this "Awesome" plugin a dead project now…???

This used to be a great plugin. But looks like it is almost a dead project now. Support threads go unanswered. This plugin no longer purges cache on new post/post and comment updates. Nothing happening in github “https://github.com/rtCamp/nginx-helper” either in last 7 months or so. Please take a call. Please declare this as a dead project if no further development is happening.
