Yeah, modded Xbox and PS3 users have been hacking achievements and trophies for about a decade, there's a long history of highest PS level/gamerscore people paying for 100%s and, most commonly, using saves (hacked or legit) that people make before trophies/achievements unlock that have been resigned to the user's profile with a simple program, allowing them to boot other users' saves up and easily acquire trophies/achievements. All of the Souls games on consoles were filled with Mega Mule save users who started the game off with access to all equipment, items and max levels. Not to mention all the glitch exploiting and boosting and the use of microtransactions in a lot of games anyway. Console achievements are as bad as Steam ones I'd say, perhaps worse because they're more popular.

I totally agree with the "you do you" philosophy. Achievement hunting communities are really weird when you dig into them, whether it's the open cheaters who give zero fucks, the subtle cheaters or the hardcore communities who crucify their members if they suspect foul play. Ultimately it's just a little number and a bunch of teeny tiny jpgs anyway and a lot of people cheat in some way for the hard or grindy ones. When anyone can hand a controller to someone else there's basically no way to keep it legit and no point trying.
