I did a little research and it is related to 'family safe' option. Unfortunately, I'd really like to keep my items in the 'safe search' part of google products as if I change to 'safe search', then I will only have my products show up if the user has changed their settings to allow for the 'safe search off' mode. I guess google just decided to check to make sure my products were in compliance.

It'd be really cool if this plugin would allow for setting the feed for either 'safe search' or not and then filtered any offensive words based on a list of words. I'd be happy just to know where I can look to try and add this check myself. I know enough php to hack it in but don't have a whole lot of time right now to dissect the code. Any help is appreciated. I'll share my hack if anyone else is interested.
