How do you stop nuisance players spoiling your scrabble

I play EA Scrabble Origin and have recently been harassed by a player (Player2) who constantly responds to multiple games I start against "random" players. This person has had as many as FOURTEEN games going against me. Once a player has responded to my first move I am obliged to play that person unless I forfeit. It wouldn't be quite so bad if Player2 played all of the games he or she started but Player2 seems to choose games they think they have a chance in and forget about the others. I thought that maybe once they had won a game that it would stop their enthusiasm but no, still playing every game they can day or night. I appreciate I could wait until someone has already made a move but this takes many "leaves" before you come across a move already made. I have asked the EA help centre to block the player for me but their response has been abysmal so I am at a loss to know what to do next. Any ideas?
