There is a bot of some sort attempting to log in to my site about 1-2 times every second.

No login is succeeding, the site is set to "None" for registration.  But this is throwing View Profile and another module exception, along with a login failure exception, to the tune of another 100 having happened since I created this thread. :)

Is there anything short of disabling notifications in the event log for Module Load Exceptions and Login Failure?  Probably a silly question ... one would have to get into the core otherwise to detect suspect logins and block them right there.

 Silly or not ... is there a way around this?

 Thanks!

Have done that.

For anyone who ran into issues and wants to save recent log entries for data, here is what I had to do.

Via DNN 4 Less web admin, I found nearly 2.5 million log entries, most of which were these.  When the turkey found out he could not hack the site, decided to slow it down with a spam logon attack.  The same web admin only allows deleting 50K of the entries at a time.  Go figure ... One cannot delete by a date range, log event ID range that amounts to anything more than 50K.

To stop the log entries I had to set the flag in the Event Config table to False for all entries. (could not get to the UI to see which ones!)

That accomplished I finally figured out the Web Admin would only let me delete 50K of 2.5 million entries at a time.  Great way to spend a morning, having to do 50 iterations for what should only be one!

I'm sure any query knowledgeable person can figure this out but for anyone else using DNN 4 Less or similar, that 50K limit is a good thing to know.
