WPBruiser plugin

We used the WPBruiser plugin on our website, but the plugin doesn’t appear to be doing anything. The record shows that the plugin went from blocking 500 requests a day to 0 in 3 days. The specific context of the plugin is for Ultimate Member login forms. The plugin says it is still protecting the Ultimate Member login forms. However, we have tried other measures to maintain the security of our website, but it has the access issue with other plugins. So we want to get WPBruiser back to normal. I wonder whether some of you can help clarify what to do with the WPBruiser plugin. Maybe removing completely and then having the database purged of all entries? Have any of you met this problem? Any response is appreciated. Thank you.
