Can't you really see that most of these complaints are written the same way and the script is always the same?
Please read this description and check their "evidence" later. I'm sure most of them work with the same method.
It's pretty well known that live Table Tennis betting has been a weak spot when it comes to players exploiting bad lines from online books. There are tons of matches, the quality of coverage is poor, and the pace is very fast with new lines after every point which can happen as fast as every 10-15 seconds. If a player can find a live stream or update source just a few seconds ahead of the Casino, they can place wagers that they know have already won.
With that in mind, lets look at the time line of facts this guy has shared so far.
Nov 14th he signs up for 1xbit, makes two deposits for 500 and 890 USDT and places 5 bets, all of which are settled within the same hour.
He loses 490 on a soccer match and then loses 3 Tennis bets for 20, 30 and 25 USDT before the bet in question here:
Table Tennis: Fedorov vs Pinkovsky, while the first set was being played he bet 680 USDT that Pinkovsky would win by more than 3.5 points.
From his screen shot we can see that 1xBit had the live score as 7-10
In table tennis you play to 11, and you have to win by 2, which means he was essentially betting on the outcome of a single point. If Pinkovsky won the point, he would win the set by 4 points. If he lost the point, it would be impossible for him to win the set by more than the 3.5 point handicap.
This situation is exactly what it would look like if the bettor had access to a live feed just a few seconds ahead of the sportsbook.
Turns out Pinkovsky won the point. They voided the bet. And the next day he created a new bitcointalk account to post in this thread.
I don't think it's ok for any book to regularly put themselves in this situation. If their tech can't keep up with all the table tennis lines in real time, they shouldn't offer action. Or at the very least there needs to be a third party archiving all the action with time stamps so that there's proof one way or the other. Eventually, innocent bettors will get caught up in the cat and mouse game between the house and players taking advantage of them.
This situation looks pretty clear to me though. I think sarvankr made that live bet because he knew what the outcome would be and now he's playing us for fools pretending that he didn't.
