You just seem like your angry that people want to group with you to play. As far as being on ps3, your going to need to find a way to communicate eventually whether its through emotes or usb keyboard. They are probably also on ps3 and cant type fast, so they invite to make a little more time before your out of their line of sight. I just have not seen anyone attempt to troll by sending out blind invites, assuming these people are just trying to get help.
