Thanks for the link. I agree odds would be slim, but this can potentially set a precedent for others to do similar things. Imagine, in the future, a new company comes up with similar add-in claiming to scan ads, and take more data than needed. Facebook needs to be careful of that too. (though i think that is not the reason they are shutting this down, just that privacy is favorable to them in this case :)). There has to be a better way to do this, and that needs serious discussion.

Also, as an aside, the add-in records the following things: country, age, gender, language etc. and the text of the ad. Not so clear what happens when ads have personal info (or friends' names) attached like xyz likes page. Payload seems to suggest they take every bit of info so it could include that as well maybe.
