I’m using university journal portal OAI endpoints for the third time in a row to fix a typo and handle DOI lookups.

Does anyone know how disrespectful or intrusive this is considered to be?

A few years ago, I scraped arXiv and they blocked my IP almost immediately; perhaps if I had used arXiv’s OAI interface, they wouldn't have blocked me.

But I really have no idea just how disrespectful or intrusive this is!
