Hi, have just fund $500 with them (cxweb and adblade), have you good experience with them? What vertical is good on there? 
No Adblade but Contextweb is super expensive and I found it hard to scale and optimize. Make sure you get a rep and talk to him before you launch anything. The categories can be limiting and your rep will help you target best. You'd find that $500 won't get you very far there when you first start testing.
You can go CPC though - quite a big advantage but expect to pay $1+/click
Hi I have try cxweb waste my first $50 with 3,58% CTR and 0.15 CPC on weight loss cat, NO CONVERSION, I think I will change the offer
I think you should get more data and read the guides on the forum about media buying...
AdBlade is great
Next tried Contextweb
now my advice... have a bigger budget for adblade. I can easily go through a grand in a hour, so watch your spending very closely. Make sure your server can handle the traffic if you're going to be using a adserver.
As said above, GET A REP. This is required, speak to them, get to know the network inside and out and then start testing.
Can you still run diet/skin with AdBlade (without flogs/fnews, off course)?
What's their international inventory like?
What's the general attitude towards affiliates?
How much do you need to spend before you get a rep?

I don't think they allow news and flogs anymore but you can run "aritlce" style landers. They have pretty strict guidelines about comments, terms, writing advertorial etc
What's their international inventory like?
International isn't great but from what I gather they are working on it. They work with mostly US pubs so the fallout is from CA, UK, AU
What's the general attitude towards affiliates?
They would love to have brands but affiliates pay the bills and they know it.

0 - act like a boss and ask for one.
