Is btstatic.com Safe?

I encountered this URL as a script. I have been unable to find out anything about the company which is suspicious in itself. I block most third party scripts unless they are required to display the client's web content. Child safety is the responsibility of the parent or guardian. I believe that children should always be monitored while accessing anything online.

I really wonder whether some of these comments are from smurfs for companies, if the writers just didn't research carefully, or if I have simply been unlucky enough to encounter them purely in the function of a server for static ad content. But, seeing as thebrighttag only advertises itself as a data-mining/analysis service, I'm fairly certain any descriptive photos of hotels are part of ads. Also, checking myself, the assertion that ***** customer reviews are only visible with btstatic-served content allowed is completely false. While I have nothing against data-mining services as long as privacy concerns are recognized properly, that does not qualify this as a good site or useful one.
