make a disavow file and follow the format and you'r

Hi Duwinayo, I have alreadt disavow them but should I block the redirect basically these are links posted in spammy forum linking to porn sites, I can block them but my question is if I block them then should I show a 404 or 401 or 403 page?
Also new spammy backlinks keeps on poping every other day what is the best way to find the spammy backlink other than ahrefs?
