Thanks for the tips, but do not understand how I see some sites linked from facebook like porn.com

and twitter?
But addressed the question of the topic, it is worth letting the social buttons to allow adult content?

It is worthwhile to make some buttons to social sites?

and google +1?

Hello,

Do you recommend using the buttons (facebook, twitter and google +1) on pages with adult content?

For adult seo marketing google uses this metric?

Thanks,

Stroke
