Yep, so true. So I guess my wishes / question wasn’t precise enough. I was mainly hoping for a discussion about the software itself, its positive uses, and is negative uses. When I say I may employ the software myself I am of course refering to the positive uses. 
For instance say over the last five years you have made a bunch of websites that are old but have good information maybe about casino software providers:
microgamingcasinos.com
playtechcasinos.com
rtgcasinos.com
bosscasinos.com
cryptocasinos.com
Lets also say you have sites about games like this:
blackjackrules.com
pokerrules.com
slotsstrategy.com
roulettegame.com
crapsgame.com
You can now make a NEW “gambling site” that is quite useful with the scraper software that collects and scrapes your own data and content from your old sites, and basically gives rise to a new bigger and more general website.
In addition to this of course you added some new “fresh” content to the site and then also use the scraper software to pull off the history of all those games from a public domain source such as Wikipedia. (not saying thats good SEO, just an example!)
Then you employ all the (working) SEO techniques you learned over the last five years to the new site.
You also now add a search function to the site and “whala!” – now that’s the implementation I’m speaking of – totally legal, useful, and potentially money making.
