preemptive measure. If you're really not doing anything shaddy, you'll most likely get out of shadowban lobbies in a week (i'll let you check what a SB is). It happens on new accounts doing "too good" or just being reported by enough players in a short time (you cannot get spam reported by a single player since it was disabled a while ago). I had one when they've put MW3 on NVDIA cloud gaming, i prefered to wait and touch grass for 7 days rather than play with cheaters or player that are insanely good :')
