Its been on my site the last week or so http://mozshot.nemui.org its the user agent. It's taking snapshots of my games forums any idea what it is, and why its taking snap shots?
Buut is says clearly: MozShot Take screenshot of any URL Sombody installed that script and the script is working It found your website and crawled it.
Lol, not aliens from space.. It is a web service to create thumbnails of web pages. Someone just generated the thumbnails of your game forums. It is harmless so don't worry...
Seems like someone is using that service to connect to your site and save it as a picture... I guess it depends on on as to if it is good or bad.
