Most people are missing the point here.
This was not a random troll throwing games. The Issue is that Dafran was a Professional Player playing for a Team that qualified for Overwatch Contenders, so far the closest thing to OverwatchLeague we've seen so far.
In his Position he was basicly a representation of the whole Competetive Overwatch Scene, his Team and to some extend Overwatch League aswell - and specially after the exposure in Contenders somebody people look up to. He then (ab)used this Position to undermine the very nature of the competetive gamemode, ruining games for at least 5 other people every match, and encouraging his followers to do the same - influencing a lot of (potentially younger) players.
Considering how careful Blizzard has been to "get OWL right", there is no way that Blizzard would let this type of behaviour represent their Game, Brand, League and community .
After all, Blizzard, Selfless and Dafran can be Lucky that OWL isnt a thing yet and (mainstream) Media doesnt care for this yet - but as recent history with other "internet people" like PewDiePie show is that media loves this kind of Drama.
If you want to be a player in OWL you should be clear about the fact that a lof of eyes will be watching every move you do. And if you cant handle this, this is the wrong Job for you and you should keep this being a hobby rather than a profession.
