Issue with collections saying it is blocked

[CyberAngel]

I seriously hope that my collections has not been trashed, I had around 200 of them and to lose them all I am not going to be happy.

Recently I just started getting an issue where it is saying that

This content is blocked. Contact the site owner to fix the issue.

And it has propagated across all my devices because of my account being synced. I can log out and create a new account and it appears to work fine with that new account. I have even tried resetting the browser to all defaults, and I am not doing that again as I have certain tabs I keep open all the time for work and readding these was a pain!

But as it seems to be account related, how am I going to get this content back?

I am having the same issue just now; haven't used my laptop for 1.5 months since school ended so I did not notice. Losing all of my collections is detrimental to my school project I was about to continue. If I create a new profile they are all there, but that does not help me recover all of the academic articles I just lost. 

I think the worst part about things like this is that they happen for no reason at all, seemingly spontaneously, especially when one's back is turned for five minutes...
