No, i have gotten a bonuscode which i wrote in, so i choose to take the bonus im afraid.
How did you get the code, and how easy was it to find the terms that went with it?
This still doesn't excuse them for not having a system that adheres to it's own terms by not crediting a bonus, even if the code has been entered, if the deposit itself does not qualify. It's not rocket science, many complaints have been along the lines "I deposited, but the bonus wasn't added and I got the run around........ etc". It's pretty clear that casinos CAN and DO have some quite complex systems in place to ensure that no matter what codes a player puts in, only those who are deemed to qualify get the bonus. These cases have usually been found to have been a result of the player not qualifying for some reason buried deep within the terms, such as being from an excluded country. Now, if systems can poll the IP address and use this as the basis for blocking the addition of a bonus due to the country of the player, I am damn sure systems can poll the deposit methods and exclude certain ones from bonuses.
Way back in 2005, many casinos were able to automatically detect where a deposit came from as in those days Neteller users had the red carpet rolled out for them, and they would automatically get 15% extra added on top of anything else. If they could detect Neteller and credit a bespoke bonus for it in 2005, I am damn sure that over a decade later they can do the same thing, if not far more.
It's more a case of laziness, and the fact that the vast majority of players will not win from the welcome bonus, and will be blissfully unaware that if they had, it would have been confiscated. Casinos know that first impressions count, and if a player was expecting a bonus which they would probably lose, but might occasionally win from, if it isn't credited it is likely to give a bad first impression, and the player may just ask for their deposit back and will play elsewhere, even though it might ONLY be the welcome bonus that has these rules, and had they not been put off by a negative first impression, they would be OK regardless of deposit method.
Those Neteller players who lose the bonus they shouldn't have got may carry on playing because they would never have any idea they would not have been paid had they won, so the casino has kept a number of players it would otherwise have lost had they not been given the bonus they lost in the first place. Of course, they have lost a smaller number of players who won with the first bonus, and didn't carry on playing because their win was confiscated, and the longer they played, the more likely they would have ended up losing to the house edge overall, even despite the initial win.
