If you can get rid of it then get it removed else just focus on building more backlinks - quality over quantity!
You can not control who links back to you. Search engines will not hold you accountable for backlinks, but only for who you link to.
Thank you. I know, but I don't want to visit the site, because it is a adultsite, strange, I don't understand why they placed a link to my site, because its about health ect.
Carry on then and just try to make more quality backlinks now as you really can't control who links you back on this vast web world.
You can contact the webmaster to ask for your link to be taken down. Alternatively, you can ignore it because it will not hurt you as search engines understand that we do not have control over external links.
I know you don't have control about bad links, but I don't like it I'm glad that is not a bad for your site, that is want I want to know, thank you.
if i were you, if i have nothing else to do in putting out all bad back link, i must do some technique in building my quality link, an so for, my site stay its quality.
well, just because its from an adult site doesn;t mean its a bad backlink. you can say its not a relavant link as your site is related to health. therefore you will not get credit for link relavancy, but there will be no penalty. as others above suggested, no one can control who links back to the site. i would not worry about it myself but if it bothers you, as sugegsted above you can contact the webmaster ask ask for explanation or request your link to be removed.
