True or False: The disavow tool should be used carefully and is best used when sites are clearly malicious and haven't responded to removal requests.

The disavow tool should indeed be used with extreme caution. Its primary purpose is to inform search engines like Google to ignore specific backlinks that are spammy, low-quality, or clearly malicious, which could negatively impact a site's ranking. This is particularly relevant when a site has made good-faith efforts to remove these links by contacting the linking websites but has been unsuccessful. Incorrectly disavowing legitimate links can harm your site's SEO, as it tells Google to disregard valuable signals. Therefore, it's a tool of last resort, not a routine cleanup mechanism.
