Spam messages from friends starting a game

I don't know if it's just me, but every time a friend of mine opens a game Hydra starts spamming messages from games he's opened before, I'll explain to make it clearer, if my friend has opened Doom Hydra will notify him, the next day if my friend opens Red Dead 2 Hydra will notify him of Doom AGAIN and also Red Dead 2.

Red Dead 2, this has been a very annoying problem as the games pile up and the notifications become unbearable.
