RSS feed hacked? Or not?

I'm not an expert on RSS so it's possible I'm concerned about something for no reason. I just tried a handful of Google searches to find out where my page shows up and I came across a link for the following URL:
http://photos.miseast.org/hack/feed.mg?Type=search&Data=glaciers&format=rss200
This appears to be a feed for photos on Smugmug matching the word "glaciers". Just to be sure, I went to the Smugmug homepage and searched for "glaciers" and then clicked the RSS feed to get this URL:
http://smugmug.com/hack/feed.mg?Type=search&Data=glaciers&format=rss200
The resulting RSS feed is almost exactly the same as the one from the first link. I guess I'm a little bit concnered because the first URL is not from a Smugmug domain, but maybe that's entirely normal. Can someone tell me if I should care about this or not?
Thanks,
Dale

Maybe I just don't understand something fundamental about how RSS works (which is entirely possible), but it seems strange to find these feeds through URLs other than Smugmug or my own domain name.

I kind of assumed that an RSS feed containing images from my Smugmug site would have a "smugmug.com" URL or my custom URL. Some of the feeds I posted above are coming through URLs I have never heard of, yet they contain MY images. I don't understand why that's the case.
Like I said, I have never really used RSS and probably don't understand something really basic, but it just seems strange that my images are being fed via an RSS feed through a site I have never heard of.

But does that mean that other people are allowed to re-publish the feeds on their own site?

The sites mentions in the URLs: photos.miseast.org, www.andtherewaslight.net, etc are actually domains that point to pro-user's smugmug accounts.
And it's possible from anyone's smugmug account to get an RSS feed of the entirety of smugmug, for a specified search.
Combine the two together, and you can get an RSS feed of a specified search of smugmug, from URLs that look nothing like the smugmug URL.
My next question is the following: does allowing RSS feeds of the entirety of smugmug being published under a "vanity domain" give undue advertising of that domain, when the photos in the RSS feed belong to a completely different domain?
In a way I don't mind that my photos are showing up in those feeds because if anyone clicks on one of the links it drives traffic to my site. I was just worried that maybe someone else was publishing my photos online somewhere, when in reality they are feeding from Smugmug.

Anyway, I also wonder if part of the worry is the use of the word 'hack' in the URL?

I suppose this brings up another question -- Is there a Smugmug feed out there which uses my custom domain (dalebaskin.com), and that I am totally unaware of, that is showing off a bunch of photos from another user's Smugmug page? I can see a possible problem with this: The feed could potentially be showing photos that I either find objectionable or that I don't want to be associated with my site. Examples might include photos that are sexually suggestive or photos from another photographer trying to sell pictures that compete with mine. In the latter case I would hate to have those photos found through MY domain name. :nono
