I do not understand how it is possible in any country to be able to charge somebody for a service on the Internet if there is no contract nor Terms of Service.
If you are an advertiser with BidVertiser, that is the situation. This I can prove.
I did use the Google search engine for this site and there were a lot of threads that had some reference to BidVertiser, but I couldn't find anything about this.
Just to repeat, I am not referring to publishers with BidVertiser. I am referring to advertisers. And there is absolutely no ToS that an advertiser has to agree to when they sign up to do business with BidVertiser.
