Destroys website

A simple replace of a single word in posts does not work as intended: all URLs that happen to contain the word are also changed, and for example e-mail addresses.

There should be a clear distinction as to what is being modified and options to include or exclude URLs for example. There should be warnings when high risk tables are being modified, such as wp_options.

There should be a distinction between replacing text in human/user readable content and essential system data.
