Its not uncommon for groups to do this. Some of the smarter casinos will do something like:
new player X from an a high risk chargeback country, using a high risk chargeback method max deposit in first week is $200
new player X from an a high risk chargeback country, using a low chargeback method max deposit in first week is $400
new player X from an a low chargeback country, using a low chargeback method max deposit in first week is $1K
And as time progress, rules such as.
If the player has been a member for 1 month, deposited x times, not chargebacked, their max deposit per month might increase to 2K
After 3 months it might increase to 10K.
Off course this can be manually over ridden by the casino/poker/sportsbook manager so that a player might be deemed safe from day 1. But a review should take place.
One of the extreme experiences I had was a poker player who came in, and deposited 180K in the first 3 days. While good – it set of a lot of alarms.
The transaction fees on 180K deposited in 3 days was also quite crazy.
