Updated site after seeing many reported errors

4/20/2019

There has, recently, been a huge increase is the website reporting bad queries - something taking the contents of the address bar, corrupting it and resubmitting.

No big deal but irritating to get dozens of emails telling me that the website had a problem.  (There is an automated mechanism that sends an email when a crash would have occurred).

I implemented a log so that I can easily see what hits the site is getting.

Bizarre, many hits from most unlikely places, Poland, Russia, Singapore, Japan, Thailand etc.  

The site is being crawled by many bots, most are legitimate search engines, but a few are bad actors.

Much research on Bad Bots etc. and I have made a start on blocking these guys.
