To get an idea, I simply go to the Users page of a site (https://meta.stackexchange.com/users) and type in the word 'reinstate' in the filter to get an idea how many. There's 36 users per page.
At the moment, there is 154. I've watched this over the past couple weeks, and it has slowly and steadily grown. Given the number of SE users, I question whether that is enough to get any attention by SE employees. And even if it did get their attention, they would also have to care (which I also doubt). But everything has to start somewhere.
