I actually bid before, expecially in 2 cases:

When i have bidded on some player 40 mins before and one tard arrives trying to snatch it when 1 min is left, hoping i'm not online: i absolutely do not bid further and as soon as the poor soul thinks i'm offline he won't add a second token in the elimination round, hence i bid last second and snatch the player for 2 T

Same of above for when we go at 1 or 2 last ppl bidding over someone: you would be surprised of how many peeps forget to bid further on the very next round and my last second bid wins over them.
