1. That is the ultima ratio, but something any tournament host should keep in mind. Just tolerating bad behaviour is not the way to go.
2. Again, nothing prevents someone from hosting a tournament. Asking for others to host something is one thing, them expecting you to do anything in regards to it is another. However, if you host something lengthy you may want to check each others timetable, but that's about it and that's also optional.
3. It's a littly baity, but the mere usage of "simp" will not get you in trouble. However, the post itself may be provocative and considered flame baiting, this is where it gets problematic. Causation and correlation, not the same thing.
4. The point of a false sense of entilement still stands, as it makes a ton of sense when you consider the context of calling for someone to "be less of a simp and do X instead".
Also some general notes regarding mod action on this forum: Just calling someone a dickhead will usually just be a verbal and have the ad hominem snipped. That is mostly relevant for on-topic threads, the off-topic may be a little more lenient, depending on context.
However, repeated display of that behaviour calls for warnings with points, which stack and hence the mute may escalate. One offense is not like the other in terms of punishment, because that factors in your track record.
You may also just not want to insult others in general, but rather prove them wrong and engage - if necessary - in a civil manner instead. If you do that outside the forums is of no interest here, but it's generally good advice.
Regarding the event itself:
I've had my fair share of disagreements with the admin staff over the course of seven seasons by now, obviously that happens and things are not perfect, but they're working. If anyone is fed up with the work of the admins, just start a competing event and things might improve.
The player base is small, but it surely can't grow much if the attitude of a lot of players, or even some entire teams do not improve. So maybe those dissatisfied with BEAST should indeed start their own event. Weren't there calls for division S? Make an invite-only tournament if you are interested in something like that, it's really not that difficult, it just requires effort.
also this - and that is from someone who is not exactly a saint either ;)
I've been criticizing and complaining since season 1, haven't been told I was insulting by anyone. Guess its how you go about things.
