A few times a week, I'll send out requests for charger items to nearly everyone on my friend's list (over 600 but I constantly try to cut back). I ask for things like mobius bow, pistols, etc. Inevitably, I receive a reply saying something like, "I sent the item you requested, please send me *item*". The item is not a charger, but a collection item, and typically one that is hard to find such as roses or an upper level rare item. It's not a rare item that I have several of, it's one that I only have one or two.
The person asking is not someone that has helped me out before either. There are some on my friends list that I give generously to and they have done the same for me.
What do you typically do when something like this happens? I have been ignoring it or occasionally offering another item on their wish list. My level is around 135 and the people asking are around level 50 - 75.
