Use wt_spamshield with comments¶
Add TypoScript Constants¶
plugin.wt_spamshield.comments = 1
With the setting in the constants you can enable or disable the plugin on different pages.
Normally, you don't have to configure anything else. Akismet integrates automatically. Nonetheless, it is possible to enter other names of the form fields in order to configure wt_spamshield/ Akismet for comments.
