Answer 1

why game?
options are possible here, but a domain is needed for analysis.
where did you get the domain? if bought, these are the pages of the old site that the bot is trying to scan out of old memory.
and a lot of 301 redirects - where are they configured? well, someone put a 301 redirect on the site or server

Answer 2

You can't see the url on the image. There is nothing incomprehensible there, the one that I saw was the Google analytics tag for clicks on an advertising company, I don’t see any further. In robots.txt, you need to close the pages that you do not want to be indexed or using the noindex tag.
