Why was the Price rush thread removed

Because it included a compliment for Betfair for nipping the cheats in the bud. When these people first started employing agents to break ticketing rules and transmitting other peoples data they didn't have permission to transmit to operators colluding on here, betfair were right in the vanguard of getting them banned and if appropriate reporting the scum to the relevant authorities they had agreements with.
Betfair brooked no favour to ex-employees and built their long term strategy around protecting new in-running punters by ensuring they were having a value experience betting only against those using the same authorised data streams as they were.

For saying that, the thread got pulled.

bongo , how are people cheating ?

Here's one example from cricket:

Courtsider are inputting ball by ball outcomes into an app on a mobile device in their slacks, and that private data-stream may be being attempted to being used by someone on here to get their way to the front of the betting queue, or hoover a price which will be out of sight two seconds later when that ball going for 6 is brilliantly caught a foot inside the boundary.

The ticketing terms of the event are clear typically stating:
'The Ticket Holder shall not, except for personal, private non-commercial and non-promotional purposes only, and in any event not for commercial gain, make or use, broadcast, narrowcast, telecast, transmit, publish, disseminate, reproduce or circulate by any means. . .'

Betfair's own rules are also clear enough on this:
'Specific Conditions relating to your use of the Exchange
    Your Conduct
    You will at all times act in good faith in relation to the counterparties to your bets struck through the Exchange and such counterparties will be able to enforce this duty directly against you. In particular you will not place bets on the Exchange in breach of any sporting rules, regulations or code of conduct which apply to you.'

Some people dont like the accusation that using an unauthorised data feed, in other words courtsiding, is cheating.
The people doing it are:
Accepting the Rules of the event when they buy their ticket.
Breaking those Rules they have accepted
Doing so knowingly and
Doing it for financial advantage

If that isn't a definition of cheating, then I'd like to see a better one. Heck, when you watch children play a board game, there doesn't even have to be a financial advantage for someone breaking the rules to be accused of cheating.

To their credit Betfair have been at the fore front of preventing this. If they hadn't stamped it out early, then ex-employees could probably have formed some kind of sporting data related company operating on cricket and tennis paying 60pc premium charge I would expect by now which would initially mean more to the short-term business bottom line than more of the skill based players on 20pc premimum charge.

But betfair didn't let this happen, and took the long term view that such cheats should be sanctioned as per their rules.

i see your point

No problem rcing, it was a polite question from you.
