I hate new players

I found a new player, like lvl 13. Username either R1VOL or R1V0L. He only have 1 badge and it was the adventure time badge. I just hit legendary on AT So I added him. I sent him a random common for common trade with note saying “1. What’s your fav AT song. 2. Guess my fav and you get 4k coins” I was going to give him his fav and possible 4k. He declined with the laughing emoji, unadded and blocked me. I just don’t get it
