I'm getting a lot of Defender 404 lockout notices all day for an events plugin, it seems, which I removed last week:
We've just locked out the host 169.48.66.93 from https://mysite.com due to more than 20 404 requests for the file /events/action~stream/tag_ids~110,145,102/request_format~html/cat_ids~1394/. They have been locked out for 300 seconds.
Not sure why I'm getting these notices when the plugin was removed or is it the database tables? I wonder if the request are coming from RSS request from the previous events posts?
