This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
Use wt_spamshield with t3_blog¶
Unfortunately, the extension is not ready for TYPO3 6.x. Therefore we didn't put a lot of time into implementing all the possible spam checks. Nonetheless, it is quite a good blogging extension.
Add TypoScript Constants¶
plugin.wt_spamshield.t3_blog = 1
With the setting in the constants you can enable or disable the plugin on different pages.
