Disable "Powered by" text in plugin

Hi There,

I’m wondering how we can disable to frontend “Powered by” advertising? Shouldn’t there be an option somewhere? Per ww.wp.xz.cn plugin guidelines:

https://ww.wp.xz.cn/plugins/about/guidelines/

The plugin must not embed external links on the public site (like a “powered by” link) without explicitly asking the user’s permission. Any such options in the plugin must default to NOT show the link.

I don’t remember the plugin ever asking if this was OK nor do I see any option to disable it.

Thanks for the help!
