Titles that are not allowed include (but are not limited to):
Basically anything that encourages viewers to upvote your post whether directly or indirectly, or to interact with your content in an inorganic way. These types of titles make the sub look spammy. Keep the titles fun, original, and entertaining.
If you use spammy/soliciting/pandering/vote begging/overused/unoriginal titles, your post will be removed and you'll probably be banned.
Just please don't do it.
And a reminder that advertising of any kind is a permanent ban.
