It looks complicated but its not and it may not be what you want, if not, someone may find it useful.

Code:

Dim myString1
Dim myString2
Dim txt1, txt2, txt3, txt4
dim FilteredStr

txt1 = "Bob"
txt2 = "Carol"
txt3 = "Ted"
txt4 = "Alice"

myString1 = txt1 & "," & txt2 & "," & txt3 & "," &  txt4
myString2 = txt1 & "," & txt2

FilteredStr = ReturnFilteredStr(myString1,myString2)  'function returns new filtered string

WriteFilteredStr FilteredStr       'sub to write the new string to page

Function ReturnFilteredStr(str1,str2)
    Dim strToFilter
    Dim strWhatToFilter
    Dim strFiltered
    Dim objRegex
    Dim iCnt
    Dim iCnt2
    Dim fStr

    strToFilter = split(str1,",")       'myString1 split at comma
    strWhatToFilter = split(str2,",")   'myString2 split at comma
    strFiltered = ""                    'variable to hold strings that make it through the filter

    Set objRegex = New Regexp           'Set new regular expression to handle match and replace duties
    objRegex.ignorecase = true
    objRegex.global = true

    for iCnt = 0 to uBound(strToFilter) 'Loop through myString1
        fStr = trim(strtoFilter(iCnt))  'String to Match


        for iCnt2 = 0 to uBound(strWhatToFilter)    '2nd loop to cycle through myString2
            fStr2 = trim(strToFilter(iCnt2))        'String pattern

            objRegex.Pattern = fStr2
            fStr = objRegex.Replace(fStr,"")        'If String to Match = String pattern then String to match is replaced with ""
        next

        if fStr <> "" then
            if strFiltered <> "" then
                strFiltered = strFiltered & "," & fStr   'if string to Match made it through the filter its added to the new string
            else
                strFiltered = fStr
            end if
        end if
    next

    Set objRegex = Nothing                       'object clean up

    ReturnFilteredStr = strFiltered
End Function 

Sub WriteFilteredStr(str)
    Dim strArr
    Dim iCnt

    if str <> "" then
        strArr = split(str,",")
        for iCnt = 0 to uBound(strArr)
            Response.Write strArr(iCnt) & "<br />"
        next
    else
        Response.Write "Your filtered string is empty."
    end if
End Sub
