We can't control the content of the ads so it's inevitable that some are going to be advertising things we argue against.
The UKS website gets very good Google rankings and a lot of hits so the ads have turned out to be our biggest source of income.
We can look at it another way however; every time someone clicks on an advertising link for some dubious product or service, we make a bit of money. So your chiropractors etc. are helping to fund UK-Skeptics!
If we're going to go on to do some bigger and better things we're going to need the money to finance it.
