I've been looking for something like this and FeedGuardians is really exceptional. I took about an hour to set it up for a variety of clients complete with instructions for each one so that it replies exactly on brand and it's been doing phenomenal. I'm very excited to see where this product goes. And if you manage ads this is especially useful for keeping people off of your ads that shouldn't be there (competitors that are too broke to run their own ads but comment about how "expert" they are on your ads lol).
