+Spammers may attack your project in two ways:
+
+ * Creating profiles with links to commercial web sites

+ * Posting spam on the message boards.

+Spammers will use automated scripts to do these if they can,
+but they will also do them manually.

-User profiles may be used by automated bots for advertisements. To prevent automation, [http://recaptcha.net/ reCAPTCHA] system can be used. For every profile modification it displays an image containing two words that the user needs to input. While the image is quite easily solvable by human visitors, automated systems have problems solving the CAPTCHA image, and are therefore denied access.
