A chat on subreddit /r/NoStupidQuestions

A lot of popular subreddits require your account to have x amount of karma or to be X amount old because they don't want people to spam the subreddit. There are people who will just make endless new accounts, do dumb stuff, get banned, and repeat.

Just interact, make posts, like, etc on more broad subreddits like this one and eventually you'll be able to post.
