I guess only Square Enix employees know how the report system really works. But it seems that Square Enix does not have an automatic ban system like Blizzard has. And if the "disturbing" player does not violate any terms of service then he will not be banned so quickly. And even if they ban him, he can create a new trial account very quickly, level a bard to 30 and start the troll actions again.
