Spammers get deleted

Every user that posts comments with unrelated links gets deleted. Sorry if i make a mistake, i think they are just bots and i don't have the nerve to investigate any further. So if you hate me for that write me a feedback message.
If you have any idea how to protect the site maybe with a nice drupal module, let me know. Help is always appreciated.
