If you go look it up, you’ll find that building management associations are under legal obligation to keep financial records, hold meetings, publish the minutes of those meetings etc etc just as any civic association. They have the legal right to demand that residents pay management fees set, they are obliged to publish the amounts they collect and also what they spend. Amounts due but not collected have to be made up from the general fund which all the residents contribute to, so they have the legal right to know who is not putting up thier fair share.
Again, it’s not spite or stealth. It’s thier duty to publish these lists. Some of these management associations control large sums of money and there are often some greedy residents looking for a chance to siphon some off, and those looking for evidence of fraud. Publishing everything helps keep this in check.
If you have residents in your building that won’t pay fees the management has the right to bar them from the building, even if they own thier apartment. If that fails to get the money owed the apartment can be sold by court auction to recover the money and return it to the management association. It happens all the time.
I never had anything more than a passing interest in this stuff, but then I bought an apartment and had to do some research.
