Some things are more obvious and can be deleted easily. For example, revealing private information, impersonating moderators/posters, and posting illegal info (e.g. dancer x gave me a bj).

Other things are more subjective and sometimes more difficult to decide. These are listed in #1 in the rules at:

"transmit any message, information, data, text or other materials ("Content") that is unlawful, harmful, threatening, abusive, harassing, tortious, defamatory, vulgar, obscene, libelous, that may be invasive of another's privacy, hateful, racially, ethnically or otherwise objectionable;"

"Abusive," and "harassing" are subjective. The way I usually make my decision is based on the "tone" of the post. For example, if the post is:
"I went to club X and an old dancer named Y came to my table and asked for a lap dance. I declined and she basically told me to screw myself and left the table."

Now, post #2:
"I was at club X and this old hag dancer named Y that looked like a fat version of Jabba the Hut came rolling to the table and asked me for a lap dance. What a joke. She's older than my grandmother and looked like she had an STD. When I told her to get the fuck away, she told me to suck her dick. She probably had one too!"

The second post is funnier but if dancer Y complains, it would be considered "abusive" because of the tone, while the first post, would not be, even though it still calls her "old".  This is because "old" is subjective and the tone of the post is not abusive.
