I think the latest thing is a good idea. Things change so quickly on the Internet (with regard to who earns what with what kind of stuff), there's a good chance any number of things out there about what earns and what doesn't is out-of-date (or about to become out-of-date).
Whether or online or off (but particularly online, maybe), there's always someone out there looking to copy, looking to try to piece together who is what making what and how they're making it, and planning to write about "how to make money" themselves. People aren't interested in preserving your traffic and/or earnings (and/or even in pointing out that someone who writes "x type" of material can actually earn money doing so (either with high search or else high volume).
A lot has changed since so many writing sites have closed down, and a lot of writers are making their money writing in other places. As it has become harder and harder for people to come up with some version of "acceptable quality", I think it's become more important for people to keep private their earnings (not just CPM etc.). It can be kind of frustrating to remain silent and know that x number of people think you can't earn or else aren't earning at all from whatever kind of thing (in this case, Hub) you write; but better that than the kind of "baloney" that goes on if it gets too obvious that you actually earn whatever you earn (or could earn more if you'd do more of the same).
You can't stop people from trying to find reasons to copy your stuff, but if you can honestly be out-and-out public about the fact that you don't share what you make or how with ANYONE that can also make it pretty clear to the person showing up (and maybe thinking about stealing your stuff) that there's a good chance whatever information they got from someone else may not be accurate).
Back when I was earning my few hundred dollars a month on this site, alone, I didn't really see reason to keep that all that secret (both because a lot of people were not and because this was only one of several spare-time-writing sites for me; so I didn't see that few hundred dollars a month as "serious").
Online or off, once you figure out that since there's no way to make sure someone who is inclined toward sharing information about someone else's income/earnings is to make it very clear that you share NOTHING with ANYONE about things like earnings/income and/or any changes that happen.
You can't go around cleaning up every piece of bad information that someone else puts out there about you/your earnings (or whatever); so all you can do is a) not share anything and/or not share anything about any changes with anyone, and b) make it clear to anyone paying attention to such things that you absolutely do not share such things with anyone at all. (Being, maybe, involved with some legal matters involving libel and/or slander, I may be particularly tuned into this type of thing; but in general, it never really serves anyone well to share their earningss/income information.)
People often assume because they're making money with one kind of writing that everybody else is automatically making money with the same kind; or that nobody else can make any money with any other kind of Hubs. OR, they assume something that went on "x number" of years ago has not changed (and they may even assume that if anything changes everybody makes a big, public, deal about it).
Having seen what happened in the "old days" on here, I'm all for doing on here what I do in my offline life, which is share no details about anything with anyone. Unless someone is married, it's a rare person who shares details with anyone else about money-related stuff. With all the never-ending changes that can go on with something like online writing, and with the fact that it's a rare person who truthfully shares details about his/her own income (at least with anyone other than a spouse); why on Earth would anyone even trust some of the stuff that gets put out there about who earns what and where they earn it? And if they want to trust what is probably one or another piece of "baloney information" then let them do so at their own risk, I suppose....
Whether it's this site (or maybe Bubblews) or any of the sites that are, or are no longer, out there these days; generally, (as with offline publications), if people aim to write whatever kind of stuff it is that the site emphasizes they'll earn some money Keeping in mind the "eggs-in-a-basket" thing, who earns how much with what kind of stuff (and where) "just depends". If/when sites change their emphasis then who earns what on them obviously can change. A lot of "big earners" on any site do so through less-than-desirable ways, so using them as someone to emulate, envy and/or compete with really isn't always the wisest thing (especially since solid earners are, as has been mentioned earlier on this thread, not particularly likely to make a big deal about how much they earn where).
The one problem with Bubblews people saying how much they make may be the same problem that happened once on this site, and that was that people didn't really believe money could be made and therefore didn't take the potential for it seriously enough to know not to talk/write about it. I don't even know at this point what's all that public on Bubblews and what isn't, but it's a whole other kind of site anyway, so (as they say) "whatever....." as far as Bubblews goes.
I wish.
