I was thinking of your description of the situation before sv_pure. What you wrote sounded like "sure some people completely destroyed the game but you got to see some cool skins". Skins can't make up for wallhacks, and wallhacks won't let you enjoy the skins. It wasn't a tenable situation.

Well, both. I wish less servers had enabled sv_pure in extra strict mode, but it was a solution to the wallhacking and extra loud footsteps. It was also the start of the decline of being able to run your own mods.
