I have recently magically increased my reputation to be 32k, but I still can't read those deleted replies and comments, for example here. Can I? p.s. Happy everyday!
I think this is an SE April fools day gag. They are offering "magic unicoins" that you can use to do things like (appear to) increase your reputation, etc. I am not surprised that it does not have any real effects (for example, you don't get the extra privileges that would come with that reputation). I predict that it will be gone at midnight GMT.
