Upwork might have a 'different treatment' for some people, including Ely, as he hinted in some of his previous posts (which I believe are all the result of his own doings that don't really align with the general policy, although I actually don't see any problem with some of them :D).
On this specific 'problem', I see multiple identical posts are generally OK'd by the marketplace. People have been doing it since before the recent 'changes'. For example, there was a job post from a client who have spent a lot, asking for people who can convert 'PSD to HTML', which was posted exactly the same way once every few days. Sent proposal to a few of them and never got a response ~ looks like they have a very specific criteria for the candidates.
There's been an increase in them since after the 'changes' which I believe is the result of the increase in the 'number of freelancers', leading to the clients' increasing needs to 'rotate the opportunity' themselves to find the 'right' candidates.
You just have to live with it I think, because Upwork wouldn't ban clients for doing it, although they discourage it and persuade clients to close their job post first if they want to create another one. And we're not even talking about the semi-scam repeated upload-apps jobs where the 'established clients' (they really pay) survived running they playstore scamming network here for years.
