Whooooooooooooooaaaaaa....I didn't know I wasn't the only one who did this lol.
Granted, I've only been doing it with pets. Since the pet battles hit, I found that I have several copies of over 100 freaking pets (I collected pets on all my chars lol). So I would randomly start coming up with goofy stories, and mailing pets to people. I'm sure some of them were quite rare (I actually think I sent someone a Hyacinth Macaw once lol), but I didn't care, I just wanted to be rid of them! I still have two characters I had to make just for storage, for all the pets I've yet to get rid of. I thought about leveling them and trying to sell them...but where's the fun in that? :-) Several people have sent me thank you notes, some even sent me gold or some paltry items (or pets I didn't have!), most never said anything. One guy returned the pet and said he already had three of them lol. I think I've fired off about 40 or 50 pets so far. I haven't logged in for at least 2 months now, I may have to log in and send some more pets out after reading this :-)
