It’s a toughie. Some people think indications of sarcasm ruin the fun.

I’m of the opinion that one should always clearly indicate satire due to Poe’s Law.

I like to put it in italics and sometimes attribute it to the group I’m parodying, or if an individual, I add “probably.” Observe:

“This entire thread is woke garbage. You should all be ashamed of yourselves. I’ll drive this bus off that cliff better than anyone ever has. Better than Biden ever could. Biden tried to stop the bus and fill it with illegals. Putin promised me there’s rainbows at the bottom of that valley, and not the radical left rainbows either. The kind that leads you to beautiful, clean, black gold.”
