I've a 7 year old site, it was one of my first sites. Back in the day when reciprocal links were popular I installed a program called "linkmachine".
Over the years I have aquired 100's of crappy spammy links via this program. I closed the directory to bots via robots.txt a few years ago so I should not appear to be linking back to these websites.
My questions, should I completely get rid of this installation even though I am not reciprocating? Will losing 100's of spammy links hurt my site?
