I occasionally get random invites from the tower and get bombarded with requests to help in a raid or carry some kids through a Nightfall. I do help occasionally but sometimes I'm just not up for it. I had a random tower invite asking for help on PoE. I respectfully declined...but he would not stop messaging me. So I did the Monty Python on him. What...is your name? What...is your quest? What...is the air-speed velocity of an unladen swallow? As you can see in the picture he did not know and after responding I blocked him. How do you guys handle situations like this?
