You can do this easily with mod_rewrite but using SetEnvIf gets a little more complicated (or not depending on your view).

When you set an environmental variable in .htaccess, your custom-block.php script has access to that same variable and its value. So in your script, you would need some code that would work check for that variable:

if variable bad_bot=1 { do something; }
