Repository which allows anonymous authorship This question concerns a problem related to a paper submission in the field of psychological methods. As part of the review process, I was asked by the journal's editor to provide my appendices as online documents at an author-controlled site, and not in the main text (simply to shorten the paper). Since these documents will be reviewed as part of the journal's blinded peer-review process, the authorship of these documents should be blinded as well until the publication of the paper.

My question is which research-related sites allow this kind of submission (i.e., a document which is made available by an URL, with anonymous authors)? As far as I know, sites like arXiv or Zenodo do not allow anonymous submissions.

I am thankful in advance for any advise on this issue.

Edit: I am aware that a similar question addressed the anonymous storage of research data for a paper submission. However, the responses listed there (Dropbox, supplementary material in the submission) are not useful in my case. Dropbox is only a last resort, and I am not allowed to submit these documents as supplements.
Thank you for all your suggestions. After researching possible options online, I found a web service similar to Dropbox which is available to researchers at my (Swiss) university (https://www.switch.ch/de/drive/). I think this will do, since it allows the anonymous sharing of files via links. Probably similar services are available to researchers in other countries as well. 

As a last resort, Dropbox could also be used for this purpose.
