There is heavy advertising here for Stake. Many signatures are Stake's. This isn't to say that Stake is a bad book, it just says that advertising is heavy here.
I wouldn't pay that much attention to advertisement and signature campaigns when determining the quality of a casino or a sportsbook. Besides, I don't like the way Stake and their people run the signature campaign on Bitcointalk. Anyone who spends a lot of time on this forum and knows its most quality members will realize that none of them are in Stake's campaign. A more professional campaign manager would have enabled better weekly pay rates and attention to quality and not quantity of posts like it is now.
That’s interesting to know and I didn’t realize it but now it makes sense. In many of the Stake threads, posters with Stake signatures keep repeating what another Stake person just said.
