There are a few hacks to get around it, I've seen plenty of accidental Fuze TKs of 2+, too. These kills were spaced out across the match's starting phase so it's hard to put any really specific time-frame on it - I wasn't aware of what was even going on until I'd been killed.
I've also experienced this on Terrorist Hunt, though it wasn't the whole team that was killed, and the guy got banned by BattlEye before the match ended. Similar intention.
