But it wasn't an obvious error as they had similar odds up in previous weeks...I've had bets canceled after I've made a mistake as a punter after calling up as soon as I realised. Where the market hasn't moved, they've always refunded as per my request so that's just incorrect. I've had bets cancelled by bookmakers for betting palps. It's in the rules, so you just cop it. I've also had palps paid because I didn't go screaming it from the rooftop which is what everyone should do. Keep it to yourself.
The only thing here is whether or not it was a clear error and they decided it wasn't. Good for the people who got their money here but I felt at the time it was wrong & still do, they knew they were betting an error - hence every man and his dog hearing about it & everyone telling their mates, and the amounts bet on a 100/1+ shot by otherwise small time punters, seen from betting statements showing they ordinarily bet $5/$10 units, now betting $100+ on such long odds, shows again they knew it was too good to be true. The actual outcome from memory worked out to be that about 1 in every 4 rounds, nobody had 40 for the round over the last couple of years, again showing it was a huge mistake. For everyone saying "they just took overs" it's quite clearly more than that, $101-$200 odds about a $4 pop is clearly a mistake however the number of times it actually happened wasn't considered when deciding if it was a clear error.
Have a couple of mates who have ended up with $15-$25k from this so happy for them but dare say that's the end of their Sportsbet accounts (especially if they just withdraw it) but they'd sell their account for that much without a doubt. Overall don't think "punters win" as I've seen in a couple of comments, just the group who were on the bet. Things will tighten up further for everyone else and rules will be tightened further, things monitored more closely. TBH it's a bit of karma for bookmakers replacing many of their odds compilers/traders with IT gurus with computer systems & algorithms, as no doubt a trader would've seen the volume being bet on this, looked into why and culled the market with much less than the $9mil liability they ended up with.
