Photobucket blocked them because they are trying to extort $399 per year subscription fee for those who want to hotlink images from Photobucket’s servers to display elsewhere.    You can still see the pics if you go directly to Sidehack's photobucket's page:  https://s648.photobucket.com/user/sidehack128/library?page=1.  You have to disable your adblocker though and Photobucket has more ads than AOL back in 1999. If you go there, be prepared to be gang-raped by pop-ups, loud videos about household cleaning products, and countless banners trying to convince you to buy a printed mug of the TR-606.  Photobucket sounds like a ransomware racket, I'm surprised they're not asking for payment in Bitcoin to see your own pics.
