I see that Betfair have changed there T&C's, has these items always been in there?
Suspicious Betting
12.1.1 where there is an inordinate frequency and/or highly unusual pattern of Bets (by comparison with betting norms) placed on the same selection(s) in a short space of time;
12.1.2 where there is an inordinate frequency and/or highly unusual pattern of Bets placed on the same selection(s) and where the theoretical probability of said selection(s) winning at the time of Bet(s) placement, based on the odds offered on the selection(s) at the time of Bet placement, is largely inconsistent with the theoretical probability of the same selection(s) winning calculated using their accumulated starting prices. By way of illustrative example only, if there was an inordinately large number of Bets placed on a multiple or permutation with combined odds of 250/1 (with a theoretical 0.004% probability of winning based on the odds) and that same multiple or permutation had combined odds of 12/1 based on the Starting Prices of the selections (a theoretical 7.7% probability of winning), this may trigger the suspicions contemplated by this clause 12.1.2;
12.1.3 where the integrity of an event (or events) has been called into question, including, for example, but not limited to where one (or more) of the participants in an event displays exceptional form which we reasonably believe was known to you or someone connected to you at the time of Bet placement but was concealed from the public generally in order to gain an unfair advantage in any Bets placed on that event (or those events);
12.1.4 where we have reasonable grounds to suspect that a Bet or a string of connected Bets were placed robotically, by automated means, or otherwise than through the Account holder placing each Bet manually via their Account;
