Twitter doesn't share its data with you. For instance, if you have a marketing campaign, and you'd like to know when a high impact influencer followed you, this data point isn't provided -- at least AFAIK.
I have a different motivation for having that data. I would like to demonstrate the months / probably years -- that have passed since I have been able to follow anyone with @knowlengr.
It was September when I last checked on the status of this request to fix what the CSR indicated was "a bug," and there's been no change and no update.
Out of desperation, because now I need to use this long-held Twitter account to reach out to journalists for a book project, I hope to get support attention by reposting the last message, provided below.
