To answer my own question in title:
I am receiving current sign payments directly to casino, and I have spent some. Because why not?

What about you?
Yes, that's my own answer to the question. I would be prompted to gambling more if that were the case with my signature campaign. Would it have been worth it, well I guess not but it would require stoic discipline to not use some portion of it every week for gambling. But I am glad it isn't. That gives me freedom to choose when to gamble.
