There is no way to prevent this, simple as that. Except for deliberately adding some losing bets, maybe. If you consistently beat the market, bet on odds that drop, and make profit, you will get limited.
fudge..i know theres some books that dont limit until you make your withdrawal and then limit u so maybe run it up as much as u can then withdraw might be one
1) Do not deposit and withdraw frequently. Unless you badly need the funds keep a balance in safe books - if there is one thing bookies hate more than winning players it is incurring the transaction costs of moving money about.
2) If you manage to hit a very good number at a 'sharp' book or on an exchange, it is worth the 'cost' of occasionally arbing/dutching that off against a bad number at a recreational book. By way of example I had an in-play bet on Betfair matched last night which was around 30 clicks away from fair value. I decided to take a small profit on that by arbing it at Ladbrokes. The EV of my Ladbrokes play was definitely negative but I would view that as worthwhile 'investment'.
