Post-game Harassment

Hi all!

I think I'll explain first: I played a game where a player was intentionally feeding. Consequently, it got pretty ugly in chat. After the game, I reported the player. Once I left the lobby, the player who I reported spammed me with friend requests. Every time I declined it, they immediately sent another friend request. As of now, I'm ignoring them, but I feel like this is another form of harassment. I feel really anxious and uncomfortable about the whole situation. Has anyone else had experience with this kind of behavior? Is this something that the tribunal also moderates? Am I making mountains out of molehills?

Thank you for your time and consideration.
