Cancel Competitive Search Bans You

Since the latest update competitive matches have been found almost instantly after starting search. Tonight I tried to cancel the search just after starting it and found that it had banned me for 10 minutes and deducted SR as if I’d joined and left a match. Has anyone else had this happen?

Just happened to me. Your post was the only thing I’ve found online about it so far.

Hit cancel during search. Search doesn’t cancel right away. Search then finds a game. Then cancels. Then 10 minute suspension and -50SR.
