How do I blacklist subjects on Piefed?

Hey folks, lazy and tired individual asking how do I block subjects on Piefed? Because I am for sure tired of seeing or hearing absolutely anything pertaining to weed. Seeing as I am staunchly against it's "no harm, no foul" public image. So can someone guide me on how to purge it from my feed? Because I am ready to let that part of my open expression go on this platform.

Also, let me actually get a little more preachy for a second. Let your reddit down vote arrow bullshit go people! It's so bullshit. Let people talk. Even if they're saying stuff you don't like. Don't give in to that skinner box bullshit. Whoever thought - let's integrate this shit into an open forum - eh! Eh to you I say. What I wouldn't give for the old way of things, because people should be able to say what they feel and every asshole has a right to express themselves. And you can gain some things from walking on both sides of the fence. Seeing something that makes you want to punt babies, and talking straight with someone about stuff you agree on. It's just supposed to be entertaining. And it's so vicious and gross feeling when you add these reaction "boxes" and "ticks."

But eh, that's just me.

Someone - halp pls to ban subject?
