I can't mention the casinos involved yet but I'm in the process of arranging an ad deal with a group of them. In knocking out the details I explained that we wouldn't be able to take on any business, whether prepaid or not, if the casinos were involved in scumware in any way. They explained that they used to do it but the whole reaction from GPWA (they named it) has convinced them to dump the whole scumware thing.
The message is getting through.
