Bilang newbie ano po kaya ang dapat kung malaman and matutunan even dark truths about using reddits?

Bukod sa karma, upvotes, subreddit, nsfw, flairs, etc. Ano po kaya ang dapat malaman ng isang newbie reddit user like me. Like mga troubleshooting, tips, how to, terminologies, mga dos and dont's, rules, mga dapat i consider before posting, interacting with redditors and even mga dark truths about reddit. Curios lang kasi baka maka gawa ako ng di dapat, iwas downvotes and banned nadin and to used reddit in a healthy way and for a long time. Thanks
