Is safer using xss_clean global enabled or xss_clean($_POST) ?[/quote]

Probably safer to use global as you don't need to remember everytime (you might forget). Anyway, they're basically the same thing.

After xss_clean how can I get rid of [removed] tags?

Code:

str_replace("[removed]", "", $_POST)

Would this code be a safe way?[/quote]
You can always modify it if you want.
