When you submit your widget to the Widgetbox gallery, it goes through an approval process.
We may decline to include and display widgets that violate our program guidelines, including:
Invasions of personal privacy
Pornography or obscenity
Content that interferes with the functioning of the sites the widget is embedded into
Promotions of hate or incitement of violence
Violations of copyright
Widgets that aren't actually widgets. Meaning, the content of the widget has to be an actual widget that people would put on a site. It can't be an ad for widgets that live elsewhere. It can't be a widget plus its installation instructions.
Any un-altered copy of the "Hello World" example HTML/JS widget provided to you by Widgetbox.
In addition, if the widget seems broken or incomplete or otherwise unusable, we will reject it and ask you to fix the issues.
