Ironically, for years and years criminologists made exactly the argument you did: preventing crime in one place just moves it somewhere else. So, police largely didn't bother, throughout the largest crime wave in history (1970-1995 or so).

Then in the mid-90s, some new research suggested that making crime more difficult to commit in one place actually prevents crime everywhere; criminals, like most people, are fundamentally lazy, and putting up inconveniences makes them more likely to just not commit any crime at all. In the 20 years or so since, crime rates have fallen by more than half.

Some redditors probably did go off somewhere else where they could spew invective. Most just went back to looking at gifs of dogs falling down stairs or whatever.
