There are thousands of users using the Chrome Extension, probably tens of thousands of times each day (so millions per year). Very occasionally (perhaps a few times a year) a user gets locked out and receives such an email from LinkedIn, and we were actually able to prove beyond doubt that this is not related to the Ezekia extension. In one of the cases, although the user was an Ezekia customer, they had never downloaded (or used) the extension and nonetheless they got this email.
What we found was that the LinkedIn algorithm picks up on what it considers ‘non-human’ behaviour. This can simply be having many LinkedIn instances open on one computer simultaneously.
Ezekia uses LinkedIn’s published APIs, very similarly to how Google uses them. We don't ‘scrape’ LinkedIn or do anything automatically. A user is always required.
We suggest:
1. Reduce concurrent open instances of LinkedIn
2. Tell LinkedIn that you are not using automated tools, and you demand that they do not block you.
