Welcome to the Q&A Forum

I'm new to MOZ and thought I'd try it out free for 30 days, knuckle down and fix any issues with my website since I only set it up in January and want to keep it in tip top condition and try to get it ranking. Well, I made my way through each page and fixed everything and then I come to in the inbound links/domains and my eyes turn into saucers and I almost fall off my chair. I have 1 inbound link with a spam score of 78% from a site named "Nitter". How on earth do I get rid of this and what the heck is "Nitter"?!
