# Spam Prevention {#spamprevention}

The registration form of the extension may be target of spam bots, which submit the form with various data.
Besides the fact, that this may require manual work to delete all spam submissions from the database, it may
even be a bigger problem for events with a fixed amount of free places, when spam bots registrations block
valid user registrations.

The extension offers possibilities to reduce the amount of spam in the registration form to a minumum:

-   [Configurable and extendable spam check](https://docs.typo3.org/permalink/derhansen/sf_event_mgt:configurable-and-extendable-spam-check@9.0)
-   [Configurable captcha field](https://docs.typo3.org/permalink/derhansen/sf_event_mgt:configurable-captcha-field@9.0)
