Eune is NOT the most toxic server
most people in eune lack the capacity to be toxic for some reason their playerbase largely consists of young children even the insults are immature and don't give any sense most of the time if the average 12 years kid flamer in eune will trigger you then I'd worry about your mental health
meanwhile the real expert flamers reside in euw and na people they are either really nice or really mean and they could argue with you forever and then report you afterwards so you get banned they are the definition of evil and imo are the people you should worry about
just a simple observation from playing in all three servers for a while
