My site is built in Wordpress. Somebody has built spammy pharma links to hundreds of non-existent pages. I don't know whether this was inspired by malice or an attempt to inject spammy content. Many of the non-existent pages have the suffix .pptx. These now all return 403s. Example: https://www.101holidays.co.uk/tazalis-10mg.pptx A smaller number of spammy links point to regular non-existent URLs (not ending in .pptx). These are given 302s by Wordpress to my homepage. I've disavowed all domains linking to these URLs. I have not had a manual action or seen a dramatic fall in Google rankings or traffic. The campaign of spammy links appears to be historical and not ongoing. Questions: 1. Do you think these links could be damaging search performance? If so, what can be done? Disavowing each linking domain would be a huge task. 2. Is 403 the best response? Would 404 be better? 3. Any other thoughts or suggestions? Thank you for taking the time to read and consider this question. Mark
