Poco Wangzhe vs. Google? Who's Calling the Shots! - Internet News - DemoSeo.com

When adding a Poco bookmark, I unexpectedly discovered that the keyword "Google Webmaster" is restricted on Poco, with a prompt indicating illegal characters, which caused the addition to fail. Is there any feud between Poco and Google? I'm not sure how to analyze this from an SEO perspective, so I hope someone with expertise can provide guidance!
