I will try and explain the reasonings behind the banner, but please don't post the same type of message over and over again in different posts. - This will just clutter up the forum.

My website is not selling advert space to 0870 companies, and they are not sponsoring it. - The advertising campaign is currently being run through Google.

The site is offered as a FREE service to everyone (including you), and does have running costs - I'm sure most people don't mind what banners are being shown, if they are getting a free service in return.

Google do not currently have a way to block certain categories of adverts, although I have been manually blocking certain websites myself.  

Google adverts are randomly displayed based on the words used on a particular page, which is why different adverts appear on different pages.  - I have actually had positive comments regarding the adverts for 0870 numbers, that have slipped through my manual blocks.  It actually shows consumers how much money companies can make by using these numbers.

I would also like to make it clear that this is a personal site run by myself (Administrator). - I only have one person (Moderator) helping with the 'behind the scenes' checking/validating of numbers, etc.

Thanks
Daniel
