I have found some questions was held which are really Wordpress related. I found some questions are put on hold due to plugins, API, etc.... I got several tags that are available in wordpress.stackexchange.com and some people tags with them.
My Questions is:
1) If tag is available and some questions on that tag then why its put hold?
"Third party plugins and themes are off topic, they are better asked about at their developers' support routes."
Third party plugins like (pods-framework,plugin-wp-seo-yoast etc)
2) I found some third party related tags and questions are approved and some are rejected. Is there any reason to do that?
Actually, I am just trying to understand. I don't want bad contribution of StackExchange site.
