I have run into a large number of players who would choose to toggle all chains and stall until their timer runs out, once they realize they are losing, hoping that the opponent runs out of patience and scoops. This is a toxic behavior that I believe should not be promoted.
My suggestion would be to penalize players who frequently lose due to time-outs, to discourage this behavior, as people with genuinely poor internet should not repeatedly trigger this within a short period, preventing harming the truly innocent too.
