this might be best if, like previously stated, be more clarrified.
For instance if your playing and you say something and some1 responds to it in a pm, its only natural that you respond to it.
maybe its best if there could be a rule saying something like: you can respond to pms if you try to move and kill in the meantime (or engi or so) and look for a safe spot if you like to respond.
Or maybe be able to stand there for up to 3 minutes or so.
Just saying some ideas for making it easier for all in the future and to stop these kinda discussions
