It's even worse with The Sims. I remember when I was in highschool, and an avid sims 2/3 player, I found this mod that would remove the pixels from the sims when they're naked. Of course the sims by default had no genitals, and being a hormonal teenager I also downloaded a mod that would fix that issue.

Because of how modded content for the sims is, a lot of the times the download sites are just link aggregators, so to download a mod you'd be sent to a different site that actually hosted the file. Downloading the naked mod led me down a rabbit hole to a site called sexysims3.com (or something like that) that had just... Every type of sex/porn mods you could think of.

From giant dongs to incest, it was all there.

I was pretty horrified and noped out of there pretty quick, and cleared the browser history because it was a shared family computer.
