That’s fair. I guess when they mentioned they were building a PC I assumed it was relatively recent hardware. But I’ve been there when you can’t get or find drivers, or Windows tells you the old drivers aren’t compatible with newer OS’ and things like that.
As long as it’s not “spammy” and there’s actual engagement or discussion on the posts I don’t see an issue. But if the community being posted to isn’t engaging with the posts, or it’s crowding out the more interesting posts, yeah that’s not great and shouldn’t be allowed.
