I have a facebook account for which I collecting friends. Every friend is targeted according to nationality and location. I scrape the IDs via Facebook Friend Bomber from groups, events and pages. I have hundreds of IDs, but I would like to run FFB all the time and be constantly adding friends instead of adding a couple and then getting the warning that I what I am doing may be considered abusive and blah blah blah... Does anybody know the best time interval to use between friends requests?
