So you're telling me that nobody has any evidence of said events happening... even though it's such a widespread event that by now, you're used to the mods doing it?
And let me guess, the mods conveniently went and silenced everyone on Twitter, Reddit, and other platforms too, right?
And they also stopped people from filing support tickets to contact Riot directly to overthrow the tyrannical, malicious mods?
Again, proof, stop spreading lies. It's that simple.
If the mods were that open about "defending" people who use heinous language, someone would have talked about it. Also: I've been using the boards way longer than you have and haven't seen a reported case of this, I'm in a Discord where I interact with them almost daily, and literally nobody else has talked about what you're claiming right now.
