It is a reportable offense to ask other players to report someone. So if they are making up lies about you in all chat and asking other players to report you, they pretty much hung themselves. Mute them if you cant ignore them without muting them, And report them, if you feel the need to do so. False reports are just that so long as you were sportsmanlike, didn't AFK, and put forth your best effort, it is just a false report. I would not worry about it. It sucks and it does not feel good to be lied about. I am sorry you had to deal with it. But if you are in that situation, Mute/Report is the best option.
An angry student walks up to his teacher, in class and challenges him to a duel. Shouting insults, "You're an old fool! You have no strength left! I will strike you down in one blow." But the teacher ignored him, and continued with his lesson, and when class was over the student left defeated with nothing. Another student approached the teacher when all the other students were gone and said, "Teacher, why did you not take his challenge, why did you let him insult you?"
The teacher responded, "If someone brings you a gift and you do not take it, To whom does it belong?" The student thought about it, and replied, "It belongs to the one who offered it." The teacher said, "It is the same with lies, envy and insults: If you refuse to accept them, they belong to the one who offered them."
Don't accept the toxic remarks other summoners make. Do not even respond to them. Anything offered and rejected, belongs to the person offering it.
You have NO power over others actions. Only power over how you react to them.
