RegEx Sporge Filters?

[adamlau]

What are some good, useful examples that can be implemented in NB?

How does the sporge you're trying to winnow out differ from the real posts?
If it's some leading characters - that's easy.
For example, if you'd like to identify posts that start with !!!, ! ! !, ***, etc, you can use
^([!?*]\s*){2,6}
The characters in the square brackets determine the kinds of leading chars to be found, "\s*" means possibly followed by any amount of white space" and the numbers in the braces are the min/max number of repetitions of the pattern (only min really matters if you're going to put this in a reject filter).
