A global theme on the kde third party store had an issue where it executed a script that removed user's data. It wasn't intended as malicious, but a mistake in some shell parsing. It was promptly identified and removed, but not before doing some damage to that user.
Suggestion from my subjective POV: Maybe change the colour of the warning message field in Get Hot New Stuff to red instead of blue, and change the icon to a warning sign instead of an “info sign”?
The way this looks to me now is as if it’s something purely informational or some help text, and not like a warning about a possible risk of data loss or compromise.
