This Joomla! System Plugin is a extended version of our popular Joomla! User Plugin plgSpambotCheck. It hooks into several Joomla! Extensions such as the comment system of K2 and prevents spambot attempts. Plugin checks e-mail and/or IP against online spambot databases and prevents - acording to the results of that check - spambot actions. It has many options for indivudial configuration. For now it only works with K2 but I plan on extending it on other Joomla! Extension too.
