plugin review and security

I certainly hope I am posting this in the correct forum area, but I have a question; is the code of submitted plugins reviewed before they are approved to be hosted on this site?
I understand about the consequences of depending too heavily on plugins, and therefore, try to keep installs to a minimum, but since I saw a plugin today which i thought would be ideal for one of my sites, it’s called “finboo search widget”, I downloaded it, unpacked it and uploaded it to my server, but before activating it, I realized I forgot a critical step…googling the domain of the developer.
In this case, the FindBoo.com website seemed to be keyword stuffed and highly suspicious, I dunno exactly why, but it immediately gave me the creeps, I thank goodness that I didn’t activate the plugin and run the script.
While I’m here, I still think the concept of Findboo in the description (except for the gaming part) is really neat, does anyone know of a similar plugin?
