"If you have a web site and you don't want your email addresses harvested by all the spambots scouring the internet, SpamStopper is the tool for you!

SpamStopper is 100% free, but if you would like to make a donation as a way of showing your appreciation for the application - as well as to show support for the continued development and enhancement of SpamStopper - you can do so by purchasing one or more $7.00 SpamStopper Support Donations."

(What is at issue here is not usability, or creeping featuritis in possibly the world's most trivial application, but a full megabyte RB program monster to just parse a single character string - a task that demonstrably can be performed in Perl for under 300 bytes.)
