But for people who use cheats or bots or DDoS, Riot has gone out of their way to permaban those people from the game, tracking down their smurfs and any new accounts they created.

This is nonsense. You have no knowledge as to whether or not they really bother to hunt for these people. It's a very tenuous and hard task to constantly investigate each and every account IP and see if it matches an offender. They really only bothered to ban Incarnation's posterior accounts because of the famous personality he is. If he was a nobody, Riot wouldn't even bother to check.

If they're going to unban a player among the worst offenders ever, then every account that's banned for ONLY toxicity, a much lesser crime, should be unbanned, too. That's never going to happen, so therefore, this guy should never be unbanned.

Then again, this doesn't follow logically at all, in fact the atrocious level of logic you just used here is quite embarrassing and nearly unchallenged in this sub.

They'll unban the player from competitive play while still leaving the accounts with which he did those things permanently banned, which in no way requires that they unban every other toxic account (?).

If he wants to create a smurf on LAN and hope Riot never finds it to ban, fine, but to give him the ultimate reward for any LoL player, to be in the LCS, after counting him among the worst LoL players ever, is just retarded.

The objective of punishment in most civilized countries is to reform the individual. Incarnation's behaviour has improved dramatically. He's been one of the most positive players in terms of behaviour for more than two years straight. The guy was 14/15 when he did those things.

We've all done our lot of stupid shit when we were teenagers and to somehow claim a higher moral standard when this situation pertains to a reality we've all witnessed when we were younger is just intellectually dishonest.
