I wrote an email to all three core maintainers (one of them even twice) and to some of the inactive maintainers. There was no reply at all. However one reacted on github where I addressed the maintaining issues but basically just ignored it and all those who had similar concerns.

Well I am not the only one being frustrated about how things go. Especially the lack of communication. It's basically non-existent. At least the PRs that are merged are mostly either adult related or youtube. If your site is not even known to the maintainer - good luck. That will never be merged tho it may be one of the biggest sites in asia or so.
