Bulk Remove Users

This plugin is lightweight and removes subscribers ad expected.   You can easily edit the php to use for woocomemrce customers or other roles too.

It times out the page with above about 3000 users on my server, but still cleared them out.   It worked for 9000 users no problem. 

Thanks for this.

Does Exactly What it Says
