Arch Linux Now Believes Malware Incident Under Control: More Than 1,500 Affected Packages
(www.phoronix.com)
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It is a different situation, because Nix packages are part of the Nix distributdis, while AUR packages are not part of Arch.
Also,it is a huge number of packages which are each used by relatively few people. Each arch user has in average probably only a few of these.
So, it makes sense that users review them by themselves. If you can't do that, you should probably not use them.
