That is because your profile field will accept any input, doesn't really matter what is put in it. On an older board I admin for I created a simple user profile field that simply requires a zip code to be entered, if the wrong info is entered - no registration. By using a default entry and a simple regular expression it has stopped almost all spambots.

Very important! By placing a default value and a regular expression, the registration won't happen unless a valid zip code is entered. By placing the word "ZIP CODE" as a default vale the field is automatically invalid and must be correctly changed during registration.

Give it a try...
