Social media logo copyright fair use question?

[ron_mexico]

To the extent that your incorporation of the logos suggests endorsement or sponsorship of your website, your use would be trademark infringement. I would be cautious about incorporating logos into your website without permission. However, merely mentioning the websites by name without the logo is likely nominative fair use.

That being said, I'd be surprised if any of the websites you mention would strictly enforce trademark infringement in the example you describe. Also, they might have explicit terms for using their trademarks for linking purposes.
