One consistent issue we have been dealing with the last couple years are social media accounts that attack refs or coaches. Posting videos and or making inappropriate comments about coaches/referees. It has been a major disruption to the teams, as well as school in some instances. One frustration is the length of time it takes to get an account shut down, been especially challenging with twitter.
I went back through my facebook account. I went several years without using! I keep everything pretty private and secure. I do understand that many social media apps have location trackers and or public/private setting options. I believe many teenagers are not worried about these settings.
