Well, yes, I get some players at programs I dropped years ago. I have no idea where they come from, unless they maybe use cached pages somewhere. It’s a weird phenomenon.
As far as getting clicks on a property that belongs to a program you do promote, even though you don’t promote that particular casino, that’s a good thing.
It means that they are cross promoting your players and including your aff code, as they should.
So if you have a player at casinoxxx and they send them a mail inviting them to casinoyyy, they will credit that player to you since you brought him/her in the first place.
The deposits even though there are no new players just mean that some of your old players are still depositing, which is also a good thing.
So I see nothing wrong there except for the income having been flat for some months. That can happen though, especially lately.
