Right time for polling someone who th/tk you on purpose in battle = start of the round. That way everyone can see when you write the poll reason. Also remember to press M.
Right time for kick poll against someone who is delaying battle = very end of the round (obviously).
QML leechers or report to an admin or pick a good timing for the poll.
Always remember to state the reason!!!
Should be pretty clear, huh? (If you are not sure then make a ban request or ask an admin.)
If not, then prepare to be kicked/banned yourself.
