I think the main thing going wrong is that your first argument needs to be a block of code rather than a scalar. grep works by running the block of code for each element in the array and returning the number of times it was true (or, if you did @output = grep... it gives you the list of elements from your input array for which it was true... but you don't care about that).
So this
if(grep($username =~ m/\b$_\b/, @ignore)) {
print "That didn't quite work";
}
... may do what you want. (the \bs are so you only catch whole words).

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
