ThaWoj,

The database 5Dimes referred to is one many industry books share. It's an anti-fraud measure. I've never heard of anyone being put on the list for no reason - one of your details would have to resolve to an entry in the system, but perhaps it was something out of your control like a recycled IP address.

Ian,

If the line changed in the process of asking you to confirm the wager without you seeing "review NEW price" or similar, perhaps there was a software hangup and it sounds like that's why they made a good faith gesture to cancel your bet. Did you want them to physically edit your ticket? I've never heard of that being done, either you have action at the ticket's price or not.
