Hi Chris,
I admit that some ads are not what we would desire but they pay the bills!!!
If you don't like them, click on them!!! Twice even!!!
Each time someone clicks on an ad it may cost the advertiser anything up to $4 & we get around 60-70% of that & Google get the remainder.
At this stage the ads are generating a little more than it's costing to run the site.
If a few more click on those ads we could send someone on a holiday as a prize maybe???
Really though .......... I can request a certain type of ad not to appear but in reality the ads are in response to what YOU are looking up or are interested in!!!
