Powershell - Delete all lines that contain a string from a seperated file

Question

Hi,

i need to remove swear words from a .txt file based on strings on a keyword.txt file.
Example:

Input.txt contains:
We go too the zoo.
Whats the weather today noob?
Let me be stupid.
Why is it raining?

Keyword.txt contains:
stupid
noob

I want to filter out all lines that match if a keyword (line by line) in the keyboard.txt

So result.txt would be:
We go too the zoo.
Why is it raining?

Could anyone help me out?

See how this works for you:

$k = Get-Content C:\Junk\BadWordList.txt
Get-Content C:\Junk\LinesToScrub.txt | 
    ForEach-Object{
        $badword = $false
        ForEach($w in $k){
            if ($_ -match "\b$w\b"){  # match whole word only...i.e., don't find "twat" in "saltwater"
                $badword = $true
                break
            }
        }
        if (-not $badword){
            $_
        }
    } | Out-File C:\Junk\NoBadWords.txt
