A common quirk with wordfilters, often considered either comical or aggravating by users, is that they often affect words that are not intended to be filtered. This is a typical problem when short words are filtered. For example, one may see, "Do you need istance for playing clical music?" Multiple words may be filtered if whitespace is ignored, resulting in "as suspected" becoming " uspected". Prohibiting a phrase such as "hard on" will result in filtering innocuous statements such as "That was a hard one!" and "Sorry I was hard on you," into "That was a e!" and "Sorry I was you."
