WordPress

Due to a security worm some time ago, most Unix servers deny web form posts containing words such as curl , get , or mywget.

This can be a problem if you simply want to use one of those words in a post on Drupal or WordPress. The easy work around is to use the   character after the blocked word.   means Non Breaking SPace. Adding it after the blocked word works because the Unix system won't parse the command, as   is invalid.

Another solution is to break the line after the blocked word, as the Unix command containing the blocked word must be on a single line. This doesn't work if you are using automatic line breaking with Drupal or WordPress, though, so go with the first option.
