The file that the guy uses for keywords is no longer available. Also he uses Slayer 0.5, does it change anything if I have 0.6?

The tool Is not version-specific, so It works with v0.6.

I've used It and It serves Its purpose well.

Anyway, on the internet I found these two alternatives, which one do you recommend?

ileak.xyz/2020/10/arsyn-keyword-scraper-by-xrisky.html

Try both and see which of the two provides better results.
