walkerservers are hetzner resellers with btc payment option. theyre guidelines follow the same as hetzner. $10 more for the same product but u gain more security(with payment) and the software if needed.
503 error on website.
also u need to create a wjunction.txt file for proof of ownership.
and another thing, $500 isnt unreasonable for premade sites with no traffic, but more detail is needed...
1. is auto-embed or manual embed enabled?
2. how much is the server & how long has already ben paid...
at the moment with ur traffic u'd be looking at $5 a month.
lets say 10 people a day click it, now they have to convert that 2 to stay on their site to make money.
but unless you can show u making $50 a month urself on ur adnetwork from this traffic, its a no go for anyone.
