Got Banned For Inactivity

I was playing SWAT with some friends, had to run let my dog outside and I came back to a kicked for inactivity screen, understandable. However the next screen was a banhammer screen. I already have a day and a half of playtime. Why over the 400+ SWAT games would a few inactives or quits because i have to work qualify me to be banned? It would also be nice to have a timer so i know when i can play again.
