Can I report my neighbors for constant, loud swearing?

Oh, please…
Not the tired “Freedom of Speech!” argument!

Surely you don’t mean to suggest that the Founding Fathers didn’t specifically have in mind the freedom to scream “FUUUUUUCK!” at the top of your lungs whenever you’re pwned by oRc_sLAyEr678?

Are you in a house or an apartment?

If the former and your neighbor can still hear you carrying on, you’re out of line. I’ve had asshole neighbors; it’s no fun.
