Not everyone subscribes to this silly /s tag trend which defeats the intended purpose of sarcasm.
Wait.
Was that sarcastic?
Who could say. /s is just the same as using a sarcastic vocal tone, eye roll, or hand gesture. Surely you aren't against those?
Other people can do whatever they want, I'm not against anything. And I'm well familiar with Poe's law.
Now try not being against how I like to communicate on the internet, or OP, and everyone's happy.
Challenge yourselves to write something that 5-10% of people wouldn't spot as sarcasm. I'm sure you can manage that!
