I can only find a list of recommended image hosting sites:
https://www.forumophilia.com/topic53075.html
Nothing about banned sites, although I believe there are a couple which could be put on such a list, e.g. stooorage.com which tried to gain access through port 50562 13 times in 15 seconds without me viewing any pictures at all.
I believe most of those free image hosting sites track IP addresses....
(Well, nothing comes free really)
To be secure, always turn scripting off, use adblock (to prevent drive-by downloads thru Flash-advertisements) and visit those sites using a VPN connection.
As far as I'm concerned, image hosting sites which block the use of adblocker should be banned......
