match the contents of the thread. Do not cheat users by trying to lure into your thread with irrelevant title. Such threads will be removed.
be informative. Do not use titles that are too short. If you don't have anything to say about the content that you post that means that either you are too lazy to think or just can't be bothered which is unacceptable. A title can always have information about niches, studios and other characteristics of your content.
be unique. Do not steal titles from other members even from other forums (they can post on our board). Do not name all threads the same changing just a word or two. As for "my collection" and similar titles - everyone can name their topic as you did. It's nice when users share their collections. But if each thread would be named like yours - it would be silly.
Do not try to draw attention to your thread by using special symbols (**** !!!!! --==TITLE==--), caps look, using words BEST, HOTTEST and similar techniques. Let members evaluate your stuff, not you.
Make your titles accurate. Don't use titles that are too short or too plain. Please remember that a title can always have information about girl's appearance, type of sex performed, niche and other characteristics of the content.
