75 Meters is where old hams go to complain about life. For some reason, they are unhappy with everything and everyone and they need a place to complain about it. It's always the President's fault (regardless of what party he represents), they always have some kind of bodily issue they need to talk about, and often their mental state is so bad they forget how to act like an adult and begin cussing at everything.
I pretty much ignore the existence of 75 Meters, I just consider it "CB 2.0". Now 80 Meters (down around the DX window and the CW portion of the band) is a whole 'nother animal and is a great place to operate.
And yes, it has always been this way. Back when Riley Hollingsworth worked for the FCC a few of the worst ones would actually get their hand slapped for how they operated. But since Riley's departure from the FCC, what goes on on 75 Meters is mostly ignored.
And, since it has been going on for decades and a good number of the LIDs on 75 Meters passed a 20 WPM code test, we can rule out that dropping the code requirement is what caused this problem. The problem is crotchety old men that aren't happy with life and the world, and they feel they must make everyone else miserable too. Well, that and the lack of FCC enforcement.
So, I'm not sure if you're a new ham or not, but welcome to HF! Just ignore the 75 Meter band and you should be quite happy with HF.
