Is it still safe?

Hi, Thank you for creating this plugin.

I have heard and read lots of things about Adsense invalid activity and was searching some solution for it.

I was reading a blog post and came to know about this plugin.

Though I have not applied for Adsense yet for my site, I want to know that is this plugin still useful?

And is there anything else to do once I install it? ( From technical side )

Because this plugin is not updated since 1 year? If you are still active on this forum, I would love to get a reply back from you.

Thank you. have great time. ??
