Rescreatu is a very..."gifty" community. Which is fine, if you're into that sort of thing. 

Some of us aren't. And no matter how many times you say it, there's always someone who "didn't know". And of the folks that do know, there's always someone who thinks they're being cute by going "lol, sending anyway" after you inform them that you do not wish to receive whatever it is for whatever reason.

An option ought to be available to refuse when someone tries to send you something. That'd be far quicker/easier than tracking the thing down in your inventory, trying to remember who sent it and how many, typing the name in, hoping it's spelled right, etc., and sending it back.
