This one gives us a clue about looking at the source. Looking at the source code we are presented with a large chunk of random code and another clue

<!-- find rare characters in the mess below: -->

...Snip

With a large block of special characters it seems likly that normal characters are rare.

This was a simple one line not the use of “’ to contain the text block this helps to escape all those special charaters

text = '''Insert text block here'''
print ''.join(e for e in text if e.isalnum())

this gives us ‘equality’ which we can use in the url to get to the next level
