I tried searching but didn't see anything and I don't know if it will be picked up by someone else. I'm also posting this even if I have no experience with Starcraft, esports or online gaming scenes in general.
Here is the details offered from the Fragbite Masters tournament website:
Here is the tweet in question and it was apparently posted while playing against a female competitor.
Other quick facts from my other source (in Norwegian):
To not just make this a news piece here is some possible topics for discussion:
Would this be a model to follow?
Was disqualification to harsh a punishment?
Does this incident stand out in the competitive gaming scene?
Will tacking this kind of action open up esports to an wider audience and competitor pool?
Here is the details offered from the Fragbite Masters tournament website:
Fragbite The Ukrainian Terran Mihaylo "Kas" Hayda has been disqualified from Fragbite Masters due to inappropriate behavior in connection with out StarCraft II tournament.
Fragbite Masters have decided to disqualify the Ukrainian Terran Mihaylo "Kas" Hayda from our tournament. This was decided tonight after Hayda acted inappropriately in social media, where he wrote an offensive post, claimed to be a joke, towards his opponent. Fragbite Masters do not tolerate this kind of behaviour. We strive to bring out the best of e-sports, and the said Twitter-post showed a part we all want to destroy from our community.
"First of all, I have to say that this is terrible. We will never stand for this kind of behaviour, and therefore a disqualification is highly appropriate. We need to show the players that these kinds of toxic acts have consequences. We have learned that the opponent in question has been dealt criticism for our penalty towards Kas, but we can assure you, this decision was made completely by the Fragbite Masters staff."
Pontus Eskilsson, Head of Fragbite Masters
As Group C has already started, there will be no replacement for Kas. This means the group now contains three players instead of four.
Here is the tweet in question and it was apparently posted while playing against a female competitor.

Other quick facts from my other source (in Norwegian):
- The girl has stated that it's scary that a professional player would act like this.
- Prize money for the tournament is 150 000 SEK (around $20000€16000).
- Kas has apparently apologized already and admitted that he sometimes writes stupid stuff on twitter and hates himself for it.
- Even if the decision was taken by the tournament administration there has been some backlash against the player the tweet was directed at.
