freerolls are not exactly the first ones, who comes to my mind as needing compensation, if a tournament has to be cancelled. But if I was to just randomly say, what I would consider "fair", then maybe something like this:
1) If the freeroll is not yet in the money, then just cancel it. If people used a ticket to play, then give remaining players another ticket.
2) If the freeroll is already in the money, then distribute the remaining price pool between those, who are still in it, like apparently ACR does.
If a
poker site does neither of the above, I would not really consider it a big deal though. At the end of the day, you paid nothing, so they owe you nothing, as a lot of people have said. Even if the freeroll was part of some reward system,
poker sites are not required to offer any rewards, so its basically only a matter of having satisfied and happy customers by living up to promises.
As some might know,
pokerstars used to have a reward system, where players earned rake-back during an entire year (SuperNova), and they changed this in the middle of a year, when people were already expecting to recieve that end-of-year check from PokerStars. There was a lot of complaining about this, but at the end of the day disappointed players could do nothing more than take their future business elsewhere.
