Whats the view on people that die at the start of the round and then rejoin and join the same team again to respawn?

I've seen it done multiple times lately. And it's been quite abusive + unsuccessful at times.

Ex: Player A dies to Player B at like 2:58. Player A leaves and rejoins. Joins same team. Player A is now alive (again) with $800 but he is then killed by Player B because Player A sucks.
Just a scenario - i've not seen it SUCCESSFUL but its just one of the few things I'd see. Can post a demo if needed as I have one available in a bit.
