Con Extensions are scarce, badly maintained & rarely good
If it's not part of the default Joomla installation, quality extensions are rare. Joomla has a extensions library, but it is full of abandoned, dated or bloated components, modules and plugins.
It's common-place for a Joomla-based website to be defaced, often very quickly. This is most often due to the low quality of extensions.
