tricked into getting banned

I have just been perma banned because I was tricked in to typing "%%% %%%"!!!!! In champ select the support player on my team threatened to troll if we dint type that message in chat. then he backed up is statement by picking sion support with stormraiders witch is normal what full ad sions go. then in the begging of the game he dost walk to his lane. that was the final straw so I finally typed the message without realizing what it meant. then the sion went back to playing normally after all of our teammates said it. we ended up winning the game with the help of sion and I thought that was the end of it no other banable words were said by me. then in the end game chat they told all of us that the sion and the trynd jg were duoed and that we were going to be banned and put a link in the chat do their discord. I entered their discord and they counted down till the time that I got banned. they then posted 3 msges in the chat for the 3 of us that got banned in that game. they then went on to tell me that they were actual a third party paid by riot to clean up the community and that we were numbers 169-171 that they have gotten banned. they also told me that they are paid 30$ a ban to do this. I don't think they're bad people and I'm not mad at them. one of them even helped me find the appeal system and file for an appeal. I just don't know what to do from hear and thought he community should know.

on further notice I have been unbanned via a ticket and riot has disputed all of my claims that they were a third party company hired by riot.
