A related technique used to work so well for search engine spiders. I had some software i wrote called 'search engine cloaker'... this was back in the early 2000s... one of the first if not the first to do the shadowy "cloaking" stuff! We'd spin dummy content from lists of keywords and it was just piles and piles. We made it a bit smarter using Markov chains to make the sentences somewhat sensible. We'd auto-interlink and get 1000s of links. It eventually stopped working... but it took a long while for that to happen. We licensed the software to others. I rationalized it because I felt, hey, we have to write crappy copy for this stupid "SEO" thing, so let's just automate that and we'll give the spiders what they seem to want.

You didn't 'give the spiders what they seem to want.' You exploited a naive ranking algorithm to inject garbage into search results that real people were trying to use. That you rationalized it at the time is human. That you're still rationalizing it decades later is something else.
