Will Google suspect that useful links on our site are paid?

On our travel site, we recommend and link out to hotels and B&B’s in our niche. Our readers find it useful. They’re not paid links, so we don’t add the nofollow attribute. What stops Google from suspecting these are paid links and penalizing us?

Can someone verify ownership of my site by adding a meta tag to the body of my page?

I’m worried that someone might be able to inject meta tags into the body of my content, so they could add a “verify” meta tag and control my site in Google’s webmaster console. Will that work? Or do you trust meta tags only in the HEAD section?
