Below is Dr. Radi Khrapko's story of how administrators not only blacklisted him, but also blocked his entire research institution.


Dr. Radi Khrapko: His Struggle with the ArXiv

Radi Khrapko, Ph.D.
Professor of Physics,
Moscow Aviation Institute
125993 Moscow Russia
Telephone: 095 1589209, Fax: 095 1582977,


During 2001, Dr. Radi Khrapko had posted four papers to, (physics/0102084,  physics/0103008, physics/0103051,  and  physics/0105031.  But, in November his fifth paper "A New Anthropic Principle" was rejected:

astro-ph is not the appropriate forum for these discussions

Regards T. Schwander (arXiv Admin)

This paper was published two years later (Astronomical and Astrophysical Transactions, Vol. 22, No. 6, 2003, pp. 847 ­ 850).  Dr. Khrapko blames the "arXiv Admin" for the delay in communicating his paper's findings to the scientific community.

But the situation became worse.   He says that after he had objected to their decision to reject his paper, arXiv blacklisted his institution, Moscow Aviation Institute, blocking all further submissions from the institution and rejecting his paper submissions automatically eight times:

21 Jan 2002,
18 Feb 2002,
02 June 2002,
13 June 2002,
12 Apr 2003,
15 May 2003,
16 Dec 2003,
27 Dec 2004.

Some of these papers are now published:

Measurement Techniques, Vol. 46, No.4, 2003, pp. 317 ­ 321;
Am. J. Phys. 2001, 69.- d.405;

Gravitation & Cosmology, Vol. 10, No. 1-2, 2004, pp. 91 ­ 97, mp_arc 03-307, 03-311, 03-315.

Seven months after the rejection of his November 2001 paper, he received the following message requiring that he be sponsored to in order to post further papers:

Presently we do require a written letter of sponsorship from two preferrably trusted arXiv users and in any case your sponsors will need to have expertise knowledge in your particular field of research. Sponsorship should be enlightened and enthusiastic as if that sponsor would feel comfortable being the co-author of your works.  (The new Endorsement System was published on 17 Jan 2004)

He wrote to members of the Advisory Board, and one board member, Professor Shochet, answered him.

Dear Professor Khrapko,
I finally have received a response from the arXiv administrators. They told me that you are not black-listed, and your papers are not prevented from being considered because of your email address. Rather the arXiv referees have determined that the articles that were not posted are considered to be off of the topic of the physics arXiv. I am afraid I can do nothing more, since I am an experimentalist. If you want to pursue this further, you should contact a theoretical physicist on the advisory board. I can't tell you who that might be, since I honestly don't know who the other members of the advisory board are.

Sincerely, Mel Shochet

Dr. Khrapko thus far has refused to go through this endorsement procedure.  He feels that he has been unfairly singled out, since he was previously allowed to post his papers to and is not a new user.  He wonders why he should be required to go through the endorsement procedure when other past users of have not been subject to a similar restriction.
