Why not?
I'm a teacher that teaches teenagers so I consider myself to have a valuable input on the matter. Lot of you on here have kids so have experiences as well and should also know something about discipline and how to maintain it. You yourself are a coach are you not? Handing out warnings seem fairly lenient I feel and should do the job. People act in a way that they get away with (up to a point of course). Players dive because there isn't a punishment for it. Kids who disrupt class without any sort of consequence will not stop distrupting class. Kids that see other kids get away with stuff will want to get away with it too. Being too lenient on rules that are in place to ensure that a basic learning environment is maintained and common courtesy prevails, or in this instance a discussion forum, will make the environment worse. Adults who post anonymously and have not learned that their every thought and feeling is important to the discussion need to be told. Warning is a form of boundary being implemented. An adult should understand when they are told that there is a line that they've crossed and should not do it again. Most children do understand that. The children who don't are children who's parents go against school, against authority and allow their kid to behave however they want. Some of those kids are now adults on this forum and we shouldn't tolerate them. It's not our job to educate adults on proper etiquette and we really don't need to tolerate individuals whos only input are basically a series of angry tweets.
This is an internet forum, you are volunteers and you have a limited number of tools at your disposal. I personally think you guys should rework your approach to moderation if the goal is to get the forum more towards level-headed discussion. Use warninings, use 24 hour bans. Don't be afraid to use it. It will we work to begin with but it will save you work down the line. Making it easier for yourself is really the goal here.
I'll take my warrning/temp ban now for derailing the thread. That being said, I clicked on the thread because I was curious about the responses to the video of Rashford that came out today and I imagine that was what you had to clean up?
