I did tried all that. Problem is why they banned my first account at all? There was no reason for that and their support didn't know really why too. It was automated probably...
There are large amounts of parameters bing uses to keep the scammers out. Something or a combination of things must have triggered the auto ban.
After my first account got banned and subsequently unbanned after a phone call(same thing support does not know why) I opened another account trough a VPS with new credit card new address new (but aged email from Hotmail over 10 years). And it took my credit card and there was no ban. (so this proves the auto ban is not for every new account but rather for certain parameters in the new accounts)
email addresses from certain domains are certainly considered high risk. One too many high risk parameters in your account creation and bam! you get the ban police.
On the subject of customer service not knowing what is going on....
I have called customer service and asked quite a few probing questions, I noticed they are trained to avoid questions if they remotely pertain to the inner workings of bing and say they do not know.
On one occasion I asked the same question 8 or 9 times, time after time getting a well crafted avoiding answer. Then finally the agent when pressed and made to feel uncomfortable enough confessed they are not allowed to give out that information. this has happened on the chat as well. They play dumb when they want to.
so it appears that yes there are a lot of things the "dumb" level agents don't know (things like how to look for a cloaker or malicious code in a landing page) but also there are certain things they know very well why they happen but are trained on how to pretend they do not know. such as routine review schedule on ads and the extent of the different levels of reviews, some of which are automated and some which are done by a human. Information that would enable one to reverse engineer the process to their advantage.
Ill figure it out sooner or later.
