I hate removing links from a site. I think out of about 5000 requests over the years I only ever bothered with 50 legitimate reasons. If I'm not wrong they could just disavow? R.E Negative keywords - someone was listed in my GA for finding my site with the term 'deep fried poop'. I didn't take it personally. Actually now by mentioning it here I guess this site will rank above mine and take the clicks.
