Had this bot come from the Amazon Range
GumGumBot gumgum(.)com
34.192.0.0/10

It pulled the same image 4 times in seconds. no robots.txt file was ever requested.
Traced back one of the hot linked images to a forum and then saw this bot come in right behind me visiting the forum to pull the same image repeatedly

What was the exact UA string?

Does the robot send a referer? Annoying if not, because then they may get the actual image instead of whatever you serve to hotlinkers. (I don't block hotlinked requests, just serve an intentionally hideous NO HOTLINKS graphic. That's generally enough to make the original hotlinker take it down eventually, and is actually less work for the server.)

RE: remote hotlinking to images

Be careful. Because of mobile, wide-brush file switching to a warning type image can backfire. I've seen it on user's phones. It has to do with network caching on mobile clouds, which they all do.

I changed my code to use a specific block in each respective directory. Beside the list of (blog|forum|thread|gallery|galleries|etc....) I also list the big offenders by domain. A bit tedious at times, but more efficient & less chance of the warning image cached & served to the wrong person & ending up on my pages.

Keyplyr,
I busted a competitor actually hotlinking all of their products to our product images, I was furious.

As far as this bot, all it said was GumGumBot gumgum.com

The real irony is that wholesale hotlinking mades for a terrible user experience, as it takes hours for the page to finish loading. Especially if the offending site is too dim-witted to resize images, making each download eight times as big as it needs to be. The end result is likely to be that their users don't even stick around to buy their, or possibly your product.

Be careful when cutting-and-pasting from logs, so you show only what you want and not what you don't want.
