The problem is that many of the spams are stopped because they contain r u or u s (without spacing) with one or more characters in front of it. This will sooner or later stop someone from using some common names or other words. One kinky word is F O R U M, that can't be spelled normally.

This makes me uncertain about the use of this combinations in the filter.

What does the users think of this, and especially you, Tami, as the owner of it?
