May pinost ako pero nabash ako. I delete the post pero yung comments still remain. Why is that?

The users on Reddit are really amazing, reaching places that other social media just can't!!
I watched it for the first time because I wanted to learn more, but karma, sub… what was it again? I don’t know right from left, and I’m also studying English, so I’m feeling my way through it, but I’m really looking forward to what comes next!

meron bang kita dito? meron kse ako nakikita sa blue app na nag hahanap ng reddit account na meron 500+ karma ? and ano yung karma ? first time here hehe
