There is a public archive called arxiv.org officially ran by Cornell University but used by scientists the whole world over for posting research papers for free access for everyone. The subject areas are physics, mathematics, computer science, statistics, quantitative finance and quantitative biology, each with many subareas.
My app posts to Twitter short summaries of the papers posted each day there, in various subcategories for mathematics. There are in total a bit more than 30 subcategories and for each I created an account. My application writes only to these IDs and there is no abuse.
I checked carefully that arXiv terms of service allows this. I also checked carefully that it does not violate Twitter terms of service, or at any rate falls within the possible exceptions for community benefit. I have written it up in detail at my URL:
As can be seen, I carefully verified each provision. This was a volunteer effort for community benefit without spamming anybody. I believe there should be more dissemination of public research free of cost. It may be of benefit to Twitter also to include such high quality content as daily feeds. It is an unexpected setback that the app got blocked.
Furthermore, bot/accounts for a similar purpose are running for years; for example, by @vela running accounts with IDs: mathACb mathAPb mathATb mathCAbot mathCObot mathCTbot mathCVb mathDGb mathDSb mathFAbot, etc., about the same number of accounts as mine. The difference with my app is that the previous one is restricted to 140 chars for the summary whereas mine compiles the summary into a one-paragraph image using LaTeX, the document typesetting system for mathematicians, and properly renders all mathematical symbols, etc., and I believe this is a significant improvement and will make a lot of difference for the users.
I hope the explanation satisfactory and my account write privileges are re-instated, without which tweeting is impossible. As I put a lot of effort into it for a project of research community benefit, it will be tragic if it all goes waste because you blocked it. As my effort is nothing like spam, it is disappointing to be treated like a spammer. Hoping to hear a resolution for the problem.
