Default plugins that should be removed:
Hello Dolly!
This above list of plugins should be used as a guideline/recommendation when choosing plugins to install to avoid high resource usage and is not a list of "banned" plugins.
This is not an all-inclusive list. If a plugin is not listed here, it does not automatically mean the plugin is OK.
Banned plugins: Auto-post, auto-blog, bulk post plugins are not allowed due to the abusively high resources they consume.
