Unfair Permabans

You're confusing specificity and sensitivity. Specificity: How high is the chance that somebody that was banned is a scripter. Sensitivity: How high is the chance that somebody that is scripting is banned.

When Riot is talking about accuracy, they're talking about the first. If somebody is banned, it's very very unlikely the ban was unjustified. They're not claiming they're getting all of them.

Also: The reason Riot prefers to give broad explanations is because too detailed ones can give away the methods of how they detect scripting.

What exactly is the point of your post? You say you've done research, but have failed to present any of it.

Without actually showing some evidence your post, even though it was fairly well written, is just another complaint in a sea of complaints. You can't just say you've done research and then ask the reader to take your word for it, you have to provide some substance.

Until someone actually comes up with some evidence of mass wrongful banning there's really no reason to take posts like yours seriously. At most they are just people who are mad about their bans, and at least they are part of the very small minority who was wrongfully banned. Bland responses and "people you know" are not quality pieces of evidence.

Don't get me wrong, I would be very interested if there is something going on right now, but to quote a very crude but applicable phrase: "pics or it didn't happen."
