Hey guys so my site was spammed by a competitor when my site was ranking at around #15 spot. I did not submit disavow file at that time and kept on working to build quality links to it. Now site is ranked top 3 and only has high quality backlinks along with the spammy links built by the competitor. I want to make this site a long term project, so should i submit a disavow file or not? Will that effect top rankings if i submit those links in disavow? or maybe i should submit 50% of the links in disavow file so google knows atleast i tried to remove those links, this way maybe they will not take any manual action on the site in future? FYI spammy links are around 40000 total links according to ahrefs and 500-600 referring domains. any suggestions are welcome thanks.
