NMT:
I switched to Imgur and haven't had any issues. The only difference I could note between PB and Imgur (and the only reason I liked PB) is that PB seemed to automatically scale full-sized images when you posted them on a third-party site, while with Imgur you have to do resizing manually before posting.
Also, about a month ago someone on another forum posted an excerpt from the Imgur ToS that seemed to indicate, in harsh language, that they would murder you and your family if you posted Imgur photos to third-party sites but...I haven't heard anything about that since and I'm still alive so.....
