I have a bunch of "/index2.html" URLs showing up in my Google Analytics, is that bad?

Looking at my Pages and screens reporting in Google Analytics, I noticed that my top viewed URL in our primary category over the past 12 months was:

https://community.{my domain}.com/{category name}/index2.html

Is that something expected with how Gainsight CC is set up? Is it the sign of users trying to index the site? Why would this be? 

I’m out of my technical depth and a little sensitive by some users trying to train AI models on our community. So I’d love some clarity on what this means. My google searches and questions to ChatGPT didn’t really help me get a sense of things. 

It seems like it’s just referencing the file structure of the site, but… why/how would 161 users over the past 12 months go to that URL if I’m not using it anywhere?
