Lameness filters are textbased filters used by SlashCode-based websites to stop junk comments from being posted in response to stories.

Lameness filters include:

• Too many junk characters
• Too many capital letters
• Too much repetition
• ASCII art
• Comments which are too short or long.
• Using a combination of tags that try to break web pages.
• Too short lines of text
• Too long lines of text
• Comment titles consisting solely of "first post"

Most of these can be easily circumvented if necessary, but they usually keep most junk from being posted on sites.

Obsession with bypassing these filters successfully have led to Internet trolls appearing all over SlashCode based sites such as Slashdot.
