What happens to the abusive monk?

I know a person who is fairly expert on Dhamma and in early times practised well; meditating up to 10 hours per day. But today this person spends at least five hours per day doing physical rehabilitation due to an unfortunate injury. Yet this person is constantly harassed by a troll monk who insists this rehabilitating person become a monk. While this person spends 5 hours per day doing rehabilitation, this monk appears to spend 5 hours per day trolling the internet rather than practising meditation. For example, sometimes when this person wants to sit, their body must walk. Other times, when this person wants to walk, their body must sit. Sometimes they want to quietly breathe, but the body may cough (which would disturb other monks). What happens to the abusive monk whose actions can cause distress & trauma (to a similar fool)? Are there any suttas about what happens to evil characters and uncontrolled men wearing the saffron robe?
