Actually if both people sandbag each other and both want to call each other on it by posting an anti-sandbagging RP after the deadline, they can. I don't think it's ever happened yet, but technically both parties have the right to fight back against a sandbag EVEN IF they themselves are sandbagging.

Example: Billy posts his RP on the last day and so does Bluto. Billy decides he wants to try and get a few extra points in his favor by doing an anti-sandbag RP because Bluto sandbagged. On the flip side, Bluto realizes that Billy also sandbagged so HE TOO decides to throw an anti-sandbagging RP up... resulting in double anti-sandbagging RPs that both count and get weighed against each other.

It's always good to check with me or the GM of your show directly when you're about to take advantage of the anti-sandbagging rule though. You want to make sure that we/staff know to wait for your RP and count it. For example, just sending a quick PM saying that you're working on your anti-sandbagging RP and that it will be up soon... that way it's known that something else is coming that needs to be included in the judgement.

PS: Sandbagging can be called out even if the person only does one RP but posts it close enough to the deadline that the opponent hadn't had time to see it and address it. There is no set number of minutes or hours, and it does not have to be a set number of RPs in order for this effect to take place. If anyone ever has any questions about this, please feel free to ask me.

Sandbagging occurs when you post NO WORK before the final day, making it so no rebuttals had a chance to slip through during that time. Even one sand bag (1 RP) is enough to cause this if posted late enough. If, however, you posted ANYTHING on the RP board before the final day, you are immune to being called a sandbagger that week, even if you decide to drop two killer RPs on the final day.
