Why would someone do such a thing?
If it's really bothering you, and you are positive you are not interested in him, just block him.
Ok, what I really meant to say was he does send me the emotes that are not just the "smile" and "hi"; so he pays for this account. He also did the same to a friend of mine.
To be honest, it doesn't annoy me to the point of make me upset, it is just bizarre.
Then of course, when I received the message last that he was "Thinking of (me)", I had to send the emote, "Hope you get better" with the one word, "WHY?"
