Poker site security breaches?

[Bongo]

I own my own domain and use a unique email address for anything I sign up to, allowing me to keep track of exactly where people have got my email address from.

Recently I have received some affiliate spam emails (for bowmans, tony g poker and purplelounge) to addresses I made for some poker sites (fulltilt and totalbet).

Now it seems to be that whoever sent these emails shouldn't have had any access to my details and that something untoward has happened.

The questions I have are:

Has anyone else noticed anything similar?
Am I right to be worried?
What should I do about it?

If the sign in terms and conditions state that your info will not be shared and you can prove that it has come from that source then I would do something about it.

Where can I buy security breaches, are they like incontinence pants?

You can mail them and ask to be removed.  Personally, I don't bother.   I have two hotmail accounts, one of those gets all my subscription things and any junk mail goes there too, I get loads of spam emails, but it all goes in a folder and usually gets deleted.  I have a quick scan each day and that's it.

Just block sender and ignore them, it's not worth the hassle in sorting it all out imo.

It's not the site themselves that have emailled me but some third party with some affiliate spam.

Thus my concern - How did a third party get my details? What else could/did they get? Some of these sites collect very sensitive information about people...
